Grenade
« on: December 31, 1969, 06:00:00 PM »
Ball NPS Score: 100.00
- Coverstock: Retrothane
- Weight Block:Photon Core (14-16)
- Ball Color: Navy Blue All colors do vary somewhat from the picture shown.
- Ball Finish: 2000-grit Abralon
- Track Flare Potential: 3-4 Inches (Med) on a scale of 1-10 Low-High
- Recommended Lane Conditions: Medium-Light Oil
- A few tiny pit holes in the cover stock of the ball are normal
- Description: At Roto Grip® we pride ourselves in providing a complete line of bowling balls in both value and performance. With a medium RG (2.58) and medium differential (.040), the Photon ™ core utilized in both the newly released Riot and Dark Star, is the perfect foundation for the new Grenade. You know that the coverstock is critical to ball motion, so even when testing on a shorter oil pattern, even a milder version of Sure Grip II with the Photon core was too much. We decided to step it down a notch and go ‘Old School’ with the new Retrothane™ shell because predictable ball reaction never goes out of style! The Retrothane is a traditional urethane coverstock that will help you tame even the most scorching lane conditions. As witnessed on the PBA Tour and in World Championship events, urethane is still effective today. Redefine your arsenal with the new Grenade and know that no matter what they throw at you, Roto Grip has you covered. Roto Grip – we’re pulling the pin, tossing the Grenade and shaking it up.

If this is new Grenade hits like the original Grenade, there will be pin explosions everywhere.

Layout- Pin above bridge, 5” from PAP, no hole.

Let me start by saying that I have been looking forward to this release for some time (giggity). I actually got even better results than I had hoped for. This ball is cleaner through the front than many of the other urethane balls on the market, but still maintains the smooth ball reaction I associate with urethane balls. I heart it very much. The reaction I get looks superb on the house pattern in the center in which I have my shop, but has also looked good in the early stages of Chameleon and on Cheetah as well. It is an excellent compliment to my Boomered Dark Star as well- providing a ball which starts a little earlier and is a little smoother. A very logical transition is to use the Grenade in the early part of a shift on Chameleon or Cheetah and go to the Boomered Dark Star as the lanes break down. This is totally a usable and solid piece with a throwback look and a rad logo design.

This ball does exactly what it was designed to do.  I had mine drilled pretty normal (nothing special).  This ball is probably going to increase my average by 10 pins.  This ball is perfect for someone who wants to play the gutter or just down 5.  When the lanes are fried do not hesitate to use this ball.  I went and practice on lanes that had not been oiled in two days, plenty of carry down and burnt heads and this ball was awesome.  I stood five and through down the gutter and the ball just kept striking.  I call it my hook set ball.  It reads the mid lane and then dives to the pocket and what made it even better was that it carried.  I cannot wait to use it on the cheetah.

As expected, the Grenade is very smooth going down the lane.  It does not make any sudden turns in any direction.  I have not had a ball that reacts like this in a very long time.  On a THS I found a nice line standing on 20 (with my right foot) and throwing straight up 10.  The Grenade made a slow move toward the pocket.  I bowled a game with this ball on Viper and it did not move much at all.  I was standing on 15 and setting the ball down on 3 and it was still not getting to the pocket.  I had to point it where I wanted it to go as it was only moving about 4 to 5 boards.  I cannot wait to try this ball out on a burnt shot or even Cheetah.

Grenade

1980’s coverstock meets a year 2000 core design.  Roto Grip used the Photon core found in the new Riot and Dark Star.  Just added an old school urethane coverstock and you found a secret weapon.  This won’t be a benchmark ball but I can think of several conditions that you could benefit from the Grenade:

  Short oil
  Really clean back ends.
  Long format tournaments when the oil pattern disappears.
  PBA Cheetah and Viper patterns on high friction surfaces.
  Anyone with a high rev rate.
  Great for practicing.

Great addition to the Shield line and maybe well overdue.  I would keep it away from oil,  where the reactive resins absorb oil the urethane picks up oil and can become a bit slimy.

Using the core found in the Riot and Dark Star, Roto Grip has wrapped a urethane, 2000 grit abralon finish,  coverstock (retrothane), around the core to give this ball the same Rg and Differential as the Dark Star and Riot. As the newer, stronger covers, tend to burn up lane conditions faster than in the "old" urethane days, urethane is making a return. From the novice to the advanced bowler, a urethane cover will provide a more controlled ball reaction on light to drier conditions than reactive. Altering the surface combined with proper pin placement, should give any bowler the "go to" ball that he/she needs when conditions call for more control and less reaction.
I drilled my Grenade with the pin slightly above my ring finger with an approximate 65 degree pin/pap angle. I used it on a PBA league, 35' cheetah pattern. When compared to a mutant cell pearl, I was 8-10 boards left with my feet using a much straighter line through the front of the lane. Ball reaction was good, pin hit good. As I stated, this ball is going to be condition specific depending on the individual's style.

Ball specs – 15 lbs 3 oz, 3.08 oz top weight, and a 3 1/4-inch pin.

The Roto Grip Grenade was punched using the dual angle layout method, 5-inch pin by 60-degree drill angle by 30 degree VAL angle. If you are using the Storm method, the layout is a 5-inch pin, 4 ½-inch mass bias, and a 2-inch pin buffer.  An X-hole was not needed and the finish was left OOB.  

The Grenade wraps a urethane cover around the Photon core, which is the same core that powers the Riot and Dark Star.  It has been many years since I’ve rolled a urethane ball and the same number of years since experiencing the urethane ball motion.  One word can describe the ball motion of the Grenade and that word is smooth.  With the OOB dull cover the Grenade had a tendency to pick up earlier than I was expecting but once the cover absorbed some oil that earliness went away.  Hit and carry were good.  Smooth and predictable is what you would expect from a urethane ball and the Grenade delivers both very well.  The Grenade will be a condition specific shell (short patterns, low volume patterns, extreme over-under patterns) but it could provide you with a distinct advantage on those conditions.

Drill angle – 45 Deg., Angle to VAL – 35 Deg., PIN to PAP distance – 5”, 15 lb, box finish 2000 Abralon

This ball is very smooth and predictable.  It brings me back to the days prior to reactives.  This would be a great ball to use on lighter conditions, conditions that have an over-under reaction, shorter patterns, or patterns that have uncontrollable back ends.  This is a great addition to my tournament arsenal you never know when a ball like this will come in hand to win a tournament.

The Grenade gave me a great continuous roll down the lane.  I have used this ball during my league, and it is a great ball for me to use during the breakdown.  I was able to maintain my target line, while balling down to the Grenade as opposed to making a drastic move inside.  The Grenade also reacted great on the Cheetah pattern.  It read the lanes without overreacting or rolling out on the shorter pattern.

OH YEAH!!!!!  THIS BALL IS AWESOME. OLD SCHOOL. I TOOK THE GRENADE AND USED IT ON A 35' FLAT PATTERN. THIS BALL WAS AMAZING. IT READ THE DRY BOARDS AND MADE A NICE SMOOTH MOVE TO THE POCKET. I WAS PLAYING UP 2nd & 3rd BOARD. I KNEW THIS BALL WAS GOING TO BE GOOD, JUST DIDN'T KNOW HOW GOOD. WITH THE SMOOTHER MOVE TO THE POCKET, IT KEPT THE PINS ALIVE AND DANCING AROUND ON THE PIN DECK. THIS BALL WOULD BE A MUST FOR ANYONE, BUT THE HIGH REV PLAYERS WOULD REALLY LIKE IT. AS THE CONDITION OF THE LANES BROKE DOWN, I STAYED IN PLAY WITH THE GRENADE. GREAT JOB.

I recently got a chance to use my Grenade for realin the Southeast tournament in Montgomery Alabama. I just finished shooting 660 with my Mutant Cell Pearl and although they stripped and re-oiled the lanes seemed to hook even more for the second block. I had a good shot the previous squad swinging 15 to 10,and I did't want to move any deeper so I picked up my new Grenade. It was drilled 4x4(135 degree) layout.
 I moved right to 17 and just stroked the ball right up 7 and it just walked right into the pocket strike. I threw 19 out of 24 the first two games and shot 265, 247. The last game I got a split in the 9th after iI flagged a 4 pin and shot 215.
 I didn't have to fight the lanes, just lined up to hit the pocket flush and don't look for a lot of area, I went wide 1st game 10th frame and left a bucket.
 I was surprised on my pinfall, I carried 10 pins, tripped 4's, and had morte than my share of messengers. This ball goes to all tournaments from now on. This is the low end ball I've been waitig on.

Grenade Ball Review - Ron Case

My Axis is 5 5/8 right, ¼ up, my speed is average and I would consider myself with higher revs but more up the back.  So not a cranker but not really straight either.

Drilled Pin & CG 4” from PAP.

Well it’s urethane and the definition of urethane should be, friction needed.

If you bowl tournaments and the lanes break down we all need this ball.  It’s very smooth and predictable.  It has no sharp movement which can help you when the lanes are fried.

If you only bowl on house shots you will need a lot of hand to see much movement here.

Honestly with my game I didn’t think I would ever need urethane again, but I wish I had it last year in league on the Broadway pattern.  It would’ve worked great right up 2 board.  Now I have it and I need to find another excuse.

After using my new Grenade for a couple of weeks here is what I came up with:
Layout: 45x4x40 P3 hole. Surface was left alone and just wiped down with a Roto Grip towel and an occasional shot of xtra clean from Storm.
The ball rolled wonderful on wood lanes that had a house shot of lighter volume at 37 feet. It hooked like a mellow reactive ball, but did not jerk off the spot. Loved it on Cheetah on HPL surface and Broadway on HPL and on a reverse block pointing it off the gutter at the Glen Bair tournament in Hanover, PA. The ball got me out of the jam a time or two this summer. So, if you haven't drilled one up yet... Pull the pin and watch the pins BLOW UP!

I laid out my grenade 70/5/30

This layout works great on this ball, it allows me to stay left when I am feeling lazy and don't want to move deep inside, which is a good thing. Sometimes after working the pro shop all day, I don't want to have to think alot when I am bowling. When I am in this mood, I just grab my grenade and stand left and just play in the track, which is really fun sometimes.

The grenade is super clean through the fronts and doesn't give that big back end reaction, which I what I need and want some of the time. I can see myself using this ball more than I imagined.
