I've had this drilling for a year now and it was developed strickly for a THS wall pattern. Del helped get me started with it. I could not score well on a really walled up pattern. If you read my profile you will see that I bowled on some pretty tough patterns. Everything was always over under. This pattern gives you phenomenal carry. Cuts the 10's by two thirds. It works best with a sanded (mine is at 800) fairly agressive ball. Mine is on a GP2. I have 2 300's and countless 280's and 279's using this drilling. It is the RICO drilling for THS wall patterns. It works for all types of players. "HOWEVER" ... if the wall falls apart or you ARE NOT bowling on a wall this WILL NOT work. If the wall falls apart you have usually tracked enough oil to use something else and move very little. Enjoy!

Developed with Rick Leong of (Cal) and Kenny Hall of (NY).

Out of box GP2 with 4" pin - 3 oz. top

CG is in center of the gripline evenly spaced between the finger holes and thumb hole

Mass Bias is directly under the thumb 2 3/8" from center of thumbhole to center of mass bias mark

The pin is 4" perpendicular to the right of the CG and up 1"

The weight hole is 4 3/4" perpendicular to right of thumb and down 1"

I put it on one of my Machines.  Out of the box the ball was too early, adjusted the cover to 4000 polish and it works great for my local house which has become or tends to go over/under once the heads go away.
