This drilling intrigued me. I picked up a Phenom unleashed and had it drilled up with the pin next to ring finger and the mass bias way up high on my VAL. There is a weight hole on the cg to keep the statics legal. I've thrown the ball on two different lane conditions. Both house shots during open play. I can't get the dang thing to hook or hit! It's hooking much less than my Blue Sparkle Gryphon and it isn't hitting either. I thought it might be burning up so I polished it. Even worse. Lots of length with no backend. I still have to roll it on a fresh pattern, but the initial results are discouraging. I expected this to be a control drilling, but I didn't expect it to turn the Phenom Unleashed into a dry lane ball. Is this typical for this drill pattern.
Thanx!

when i had my recharge at 315, pin was above the thumb cg belowthe ring and mb way out there, it didnt do a dang thing.

I think this woudl mostly be used for out of control lanes.

What is the Pin to CG distance?

The final layout we would like to show you can only be used on a Pin-In ball (1" or less) that has the mass bias premarked.

I wish people would really stop saying you need a short pin with a pre marked mass bias for it to be effective. That is not true at all. I've tried a 315 drill in 4 different balls all with different pin distances and got great results. As long as the static weights are legal it doesn't matter what kind of ball you're using. I've tried it in a Stinger 2 Piece with a 2-3 pin and loved it, another Stinger 2 piece with a 1" pin, a Track Mojo with a 2" pin and a Rage with a 1-2 inch pin.

One warning though, this drill is not for high trackers. I would drill this for anyone with a PAP of more than 5 1/4, especially if they were rev challenged.

Morale of the story, 315's are a myth in symmetrical equipment, and at best a gamble in strong asymmetricals - depending on the knowledge of the one making the voids in the ball.

Time for a complete plug...

Care to expand on that thought khamÃ»l? I've heard a lot of posts on here about the 315 and thought about trying one for kicks. I know they are best with an asymmetric core and short pin and low top weight. What about a symmetric makes it a myth? Why is it a gamble even with an asymmetric? Why would the driller's knowledge make a difference? As long as your PAP is known, isn't a 315 a 315? I really would like more in depth information on this subject.

khamÃ»l, I'd like to hear more about that thought also.

I've once drilled Zone2000 Limited Edition with 315degree lay-out. A 1,5 inch pin out ball as far as I remember. I was very happy with that ball. Reaction was very predictable strong arc. I was using it to control the over under on medium conditions with a lot of dry outside. But that is my only experience with that drilling and it was a symmetric ball..

khamul is correct, there is very little difference in where you place the core in a symmetric ball. It is called symmetric for a reason! If you turn the core 300 degrees to the right, it will look almost identical (i say almost because to make a pin out the core must be off at least 1/64 of an inch) to a core that is 30 degrees to the right! Guys, all you have to do is visualize it. There is absolutely no reason to drill a symmetric ball 315, it will not make a noticeable difference to anyone!

Louie, i had the same reaction at first when i drilled a freak out like that. I took the surface down to 600 on the ball and it became a great control ball for medium conditions. Lots of length with no backend should be expected from the 315, especially on strong mb cores. This ball will not be good on a house shot, however, it will bail you out when you throw on a tougher shot!

This was just under a 2 inch pin.

As long as its legal, the pin distance shouldnt make a whole lot of difference. I remember i couldnt understand at first why my freak out wasnt carrying, but once i got on a lighter tougher condition, i was thankful i had it.

When I come across some hooking lanes I'll try it again.

I was wondering if you could do it on a ball with a longer pin.
So the only thing that the short pin does is make it easier to get the weights
down???
