I'm looking to build a five ball.My pap is 4 1/2 over and 1/4 up with 15mph ball speed and about 250 revs. like playing anywhere from 5 in to about 20 and im more up the back of the ball with my hand.and i see all kinds of oil conditions from bone dry to Med-Heavy not a lot of oil around here. So what do u think of this.
1.Roto-Grip Cell=pin down
2.Grand Illusion or Rapid fire=pin up
3.Twisted fury pearl=pin down
4.Avalanche Slide=pin up
5.spare ball of course
So what drill layouts do u guys suggest for these balls or ball that i should replace them with this is just my best idea on what would help me cover everything.

1- Roto-Grip Cell is a great choice. You may also consider Brunswick Maxxx Zone. To my eyes, it is a bit more continues with a proper surface preparation. You can't go wrong with any of them.

For heavier, but typical house conditions, I'd go 3-1/2 to 4 inches from PAP with keeping enough statics for fine tuning with an x-hole. I would prefer higher pin.
For more demanding shots, based on your specs you've provided, I'd go 4-1/2 to 5 inches range and pin below to close my angles with a strong x-hole down VAL.

If it is Cell you are drilling, for your style, I'd go 45 to 55 degrees MB in both cases


2- I can't speak of Grand Illusion, but Rapid Fire is an excellent choice. My humble advice regarding drilling would be same as above.. (I'm using polished Ultimate Inferno instead )


3- Well, Twisted Fury Pearl is darn versatile! I've experimented 4 drillings with couple of surfaces. Drill it 6 inches from PAP with 70 degrees MB with a polish, it's gonna "slide" forever. Drill it strong with some surface, you don't need to punch holes in your Rapid Fire

Seriously, I'd go pin below, 4 to 4-1/2 inches from PAP with 45 degrees MB. And ofcourse, adjust the surface..

4- No experience with Slide. I haven't drilled mine yet..


Hope this helps,
