I drilled my Grenade a couple of weeks ago. The layout I used is an old school layout, axis leverage. The pin is 3 3/8 from my axis and is on my mid-plane. The cg is on my axis point with a 1 1/8 giant hole drilled through it. Being a tournament bowler, this ball is strictly meant to use on low volume short patterns. I have used it a few times now on a few different Cheetah patterns. This ball allows me to get on top of the friction and stay as close to it as I want, it never over-hooks. The reason this ball is so effective is as the games pass you don't have to change zones. Your adjustments with this ball will be to move right and slow your ball speed down while increasing your rev rate as the oil carries down the lane. Very impressed with this ball, if I am bowling on a short pattern, this ball will be in my bag. Check out the detail at www.rotogrip.com
