What I Was Looking For from this ball: A compliment in a pearlized version of the Rumble. I wanted the same aggressive backend reaction but more length.

What I Ended Up With in the Ball and Layout: A very strong pearlized ball that hooked hard on the backends. The ball would hold the line awesome even if I tugged a few or got it a board wide.

I tested this ball on a fresh pattern at my local center. The centers lanes are wood and the house shot isnt easy. The shot tends to hook early in the middle of the lanes and hang right if you get the ball too far out. Over the course of 5 games, I played around 15 and sent the ball out to 8 and sometimes went out to 5 to see the recovery. The Up Roar held my line very well and would even recover when I went a bit wide. Over the course of the next 10-15 games, the shot got much dryer in the middle and I migrated left with both my mark and my feet. What I found out is that this ball is very snappy for me when it hits the dry. With our house shot being tough and tending to be dryer off the breakpoint in the middles, I ended up moving back right and having to change hand positions to stay around the track area. I did however notice that since this ball is pearlized that it didnt recover much when I got too wide but that is to be expected on the shot we have. As long as I stayed around the 8 board no matter where I moved my stance, The Up Roar killed the pins. I have thrown this ball on a long patter as well and found that it works extremely well as long as I have a good backend.

Overall: I am very satisfied with this ball and think its an absolute fantastic compliment to the Rumble and one of the best pearlized balls out there. No over under or unpredictable reactions out of this ball like many other pearlized balls give at all. A definate must have for Roto Grip fans as well as any bowler wanting a great pearlized ball.
