got this ball last week.. and it rolls real smooth even on the most burnt of heads.... rolls pretty similar to a barbed wire by storm.. if that helps anybody

WINNERS NEVER QUIT AND QUITTERS NEVER WIN

I was shocked at this ball. I wasn't expecting as much hook as I got out of the Neptune. I put the pin at 5" under my fingers and kicked the CG a little to the right for a little negative side weight. This ball needs a little dry, but has a good reaction when you get it to the dry. I think this ball is going to keep me out of trouble. I threw it on a shot where the heads were a little drier, and I got a nice even roll. I was very impressed, not a lot of over/under.

GOT MINE LAST MONTH, THE BALLS HIGHLY UNDERATED. RT HANDED PIN UNDER INDEX, ALWAYS GOOD FOR 250 PLUS OUT THE GATE, IT SEEMS TO GET YA MID TO LATE IN THE 2ND GAME WHEN CARRY DOWN SHOWS UP IN MY BREAKPOINT ON BOTH LANES. VERY NICE REACTION OFF END OF PATTERN WHEN TRACK GETS A LITTLE DRIER OR SHORTER OIL PATTERN. THINKING OF GOING WITH A STRONGER LAYOUT FOR HEAVERIER OIL CONDITIONS. ANYBODY DRILLED ONE UP YET?

4" - 2 3/4 Top
I drilled this ball 5" x 3 3/4" with pin just above the ring finger.  Weight hole on vertical axis line 1" down.  This ball has all ready proved to be very useful on medium dry to dry for me.  Out of my hand, the roll is smooth arcing and easy thru the front.  This ball does not labor on the backends, especially playing a little straighter.  So far this ball is what I go to when playing straighter on drier conditions.

Ball specs – 15 lbs 0 oz, 3.34 top weight, 3.25” pin.  

The Neptune was drilled with a 4.75 X 65 degree layout.  This put the pin ¾ of an inch above the ring finger and the non-marked mass bias ½ inch right of the thumb.

The Neptune provided me with the cleanest look through the front ends of any Roto-Grip ball to date.  It also appeared to roll smoother (less early lope) than the other “Planets”.  The backend reaction was a strong arc and for an “entry level” ball” the hit and carry was very good.

While still not an orb for burnt conditions, the Neptune is Roto-Grip’s weakest “Planet” release to date.  On light oil conditions it will provide a very clean front end with a predictable backend move and very good carry.  The Neptune is another great release in the can’t be beat, “Bang for the Buck” Planet line.

First of all thanks to Kenny Silmard for talking me into drilling this #15, 2.5
inch pin with pin above bridge and cg under ring (cgnomaddah). And doing a great job. Kenny knocked a little of the shine off do avoid flipping at the backends. While this did give me more arc, it was checking up a tad early the 1st and 2nd games. Went back to oob finish, now I'm a happy camper. Ball carry was great and even carried a couple of off pocket hits. One team member was so impressed that he could not believe it's an entry level ball. Of course this was a newly dressed house shot. Ball clears the heads very well, retaining energy for the backend. Did not seem to over re-act to the dry. Due to my high revs and low ball speed, I think she's a keeper. This is my first review, so please be kind.

I picked up a Neptune to help combat some of the super-dry lane conditions my local house provides for league bowlers.  I drilled my Neptune with a 6" pin to PAP distance, a 3.5" mass bias (spot marked 6 3/4" from the pin on a line drawn through the cg) to PAP distance, and a 5 1/4" pin buffer distance.  This placed the pin just below and outside of my middle finger and the cg in the positive thumb quadrant.  The ball weighed out statically and didn't require a weight hole.  I adjusted the surface by applying a coat of Ebonite Extender Polish overtop of the box finish.  A photo of the ball along with my stats are in my profile.

My first league night after drilling the ball was "supposed" to be the 39' Chameleon pattern.  As typical with this house, the lane machine did not function properly and the lanes were absolutely flying to start the evening (later found out that the oil pump in the machine wasn't producing enough pressure, therefore the pattern had a significantly lower volume of oil than normal).  After a few warm-up shots, I quickly saw that all of my other equipment was out for the night (literally hooked at the arrows), so I decided to give the Neptune a shot.  Lined up with my feet on 21, crossed 12 at the arrows out to around the 5 board.  Once it reached the end of the pattern, the ball had a surprisingly strong "flip" on the backend and missed the head pin left.  The ball pushed through the heads surprisingly easy... much better than anything else I own..so I knew that I had some sort of shot.  I made a few adjustments, both on the lane to get a little deeper and with my hand position to get a little more forward roll and less backend reaction, and ended up standing around 28 on the approach and shooting for the 8-10 board at my breakpoint (usually where the lane number reflect back onto the lane surface.. around 45' down the lane).  Great length and a strong, controlled backend reaction.  I had a little room to miss outside, due to the stronger recovery of the ball, but couldn't pull the ball inside (again, bowling on a very low volume version of the chameleon pattern).  Overall, I had very good control of the breakpoint with this ball (compared to the other bowlers who where trying to throw their more aggressive equipment with tons of speed).  I experience an phenomenal carry percentage...think I left one pocket 10 pin and 1 pocket 7 pin over the course of three games.  Ended up shooting 650 to be high set on the pair.  

Providing there is enough friction, this ball seems to carry well from inside angles.  Easy length with a fairly strong move on the backend.  With my layout and surface prep, the ball definitely needs some friction to work best.  I would think that this ball could tend to be over/under if a decent volume was present on the lane or carry-down existed.  I have tried a number of other "dry-lane" reactives and all of them either hooked too much/too early, were very inconsistent at the breakpoint, or just had no recovery on the backend.  The Neptune seems to have all of these characteristics, making it a great choice for drier lane conditions.
