Had my Big Blue drilled with the pin under the bridge, and the CG kicked out to the right, HMB in the 75 degree position, similar to drilling #2 on the Hammer layout sheet. This is truly a unique ball reaction. Tried it on two different conditions yesterday, the first was after the Saturday morning junior leagues, and what I noticed was how early the ball got into a roll, but after it began it's hook, it began covering boards in a slow, methodical manner. I often have trouble with throwing the ball with too much speed, and really had to watch my speed control with this ball, since it doesn't have that hard jerky backend reaction seen on most balls today. Once I did that, it was awesome, the ball has such a predictable reaction it's almost unfair. The continuation of this ball through the pins is amazing, it just keeps driving once it makes it's turn toward the pocket. The second shot was at my Saturday night league, on re-oiled lanes after birthday parties and cosmic bowling. Not sure if there was too much carrydown for it or what, but had no trouble getting to the pocket, but left more corners than I had on the other shot, didn't experiment too much with it since it was league, but this is an excellent release from Hammer, and I look forward to having a ball reaction to go to, that few other bowlers may have the luxury of having in their bag. If you're looking for a very smooth rolling, predictable ball that can deliver power at the pins, the Big Blue would be an excellent choice.
