What I Was Looking For In This Ball Layout:
I always tell my ball driller that I want my equipment turning and burning right off my hand and I will adjust my position on the approach to make sure the equipment works for the lane conditions. I decided to use this layout based on previous layouts of my other Roto Grip equipment (Mutant Cell, Mutant Cell Pearl, and the Nomad) and the reaction I get with that equipment. I wanted to see how aggressive this ball could be even if it meant that I could not throw the ball on our typical lane conditions, typical lane conditions here are a THS 40 Feet with only one 2 to 2 in the program.

What I ended up with using this ball and layout:
I was hoping that this ball would end up being to aggressive for the everyday league conditions in my normal house. I was both right and wrong. How was I right? Given the lack of oil on the outside of our THS I could put this ball down between 18 - 20 let it swing outside of 5 and it would hit Brooklyn, on the same token I was wrong because if I put it down between 15 – 17 (I am an area bowler) and let it only get out to about the 10 so that it stayed in the oil spill that is the middle of our THS ball doesn’t miss. First two games I threw with the ball in league I never left a corner; I was forced to make a ball change in the third game because of lack of experience with the ball so I didn’t know what to do to tame the reaction of the ball going up the back didn’t flatten it but maybe a couple of boards. Left foot on 35 across 17 at first set of arrows going up the back and ball will hit the left side of the 5 pin, now that is aggression (High 4 in those two games).

Today I shot a lengthy practice session using the ball on a fresh shot, first pair we used six of us shot four games each, we all shoot a different line to the 40 foot mark. In the third game I couldn’t move any farther left (ball return was in the way) so I had to put the ball back in the locker after the four games we moved to a fresh pair for another 2 game set, brought the ball back out and was right on target again. The carry and lift this ball creates on the pins is unbelievable if you leave the 4 or 8 pin it’s because the rack was blown so high off the deck the pins flew over the pin(s) that are left standing. The speed of the messengers created at impact with the pocket by the ball is amazing you have never seen a pin go from the center of the lane to the left gutter and back across to the right gutter so fast and with so much rotation it sweeps what is left standing, like a lawnmower blade cutting grass.

What I see the ball doing with my layout is that when it comes off my hand (provided my thumb don’t stick) it starts to rev up almost in slow motion and given the swirl pattern on my ball it looks like it is easing into the gas because that swirl pattern increasingly speeds up to the tight point, don’t quite know how else to explain it, at about 35 feet the ball is at max revs and looks like it’s not going to make the turn, instead skidding into the 3-6 pocket instead of the 1-3. At about 40 feet as soon as the ball reaches the dry the ball just turns left and looks as if it just shifted from 4th gear into 5th gear and then continues to accelerate.

When the ball this transitions from the wet to the dry you can see it bite (there is a definite movement left) into the lane as if it had cleats on and with the added traction the ball has on dry the backend motion is very strong.
