Roto Grip Grenade Review
« on: May 27, 2010, 05:40:17 AM »
Bowler Specs
Rev Rate: 500 rpm
Ball Speed: 19 mph
Axis Tilt: Med
Axis Rot: Low

Layout: 40x4.5x30 (pin above middle - cg 1" right of center)
Weight Hole: none
Surface: Box

I have highly been looking forward to the the release of the Roto Grip Grenade. With the shorter patterns that we see in some tournaments this is going to be a ball that sees a lot of action.

It has been a while since I threw urethane so I just used one of my favorite layouts on this ball. I tested this ball on the Broadway Kegel pattern which is 37 feet in length. Normally on this pattern I have a hard time playing straight due to how quick the ball comes of the end of the pattern and it forces me to play farther left use wider angles through the fronts. With the Grenade I was able to play right around 5 and the ball rolled off the end of the pattern instead of jumping. The hitting power of the Grenade is absolutely awesome and unlike some urethane I have seen thrown it never died in the midlanes.

One of my favorite parts about this ball is the moves I made as the lane broke down. Normally I move 3 and 1's or 5 and 2's which widens my angles through the front and puts me in jail eventually. With the Grenade I was able to make parallel moves (1 and 1) and never lost my reaction. I felt like I could throw this ball all day and still have a look.

All in all the Roto Grip Grenade is a remarkable ball for anyone bowling on shorter patterns and for high rev players or slower ball speeds it is a absolute must buy! Great release Roto Grip!!!

I just got my Grenade yesterday!  Drilled Rico, weight hole in the CG.  The ball was taken to 4000 abralon on the spinner.  I wanted a urethane ball for a house with old beat up wooden lanes that has really tough, dry lanes.  When freshly oiled, the lanes just suck up the oil like a sponge so it changes really quick.

This ball is so smooth!  I'm a stroker, about 13-14- mph, med revs, aim third arrow or there abouts, and this ball would have a really smooth controlled arc and hits really hard.  My friend was throwing an older urethane  ball and he was having a really hard time, and he is a much better bowler than I am.  He was having such a hard time due to the lane conditions that he switched hands and started bowling left handed. But the Grenade kept hitting, smooth and hard and I only had to make a 1 board move left with my feet through out the practice session! Thank you RotoGrip for an awesome ball!
