I still have a Power Machine that is in excellent shape,but it's a 16lb. I retired it about 6 years ago when I switched to 15 lb. I had 3 of these because they were so good. I never got rid of this one. I just decided to give it a shot the other night in a local weekly tourney. I shot ok, 707 with a 278, got fast and pulled one shot. What the the biggest surprise to me was how well this ball rolled and hit! It was like I had a new ball. Now I kinda miss that 16 lb hit. Was it a coincidence? Maybe it was the ball and 16 lb combo. I'm not sure, but I really liked it, again. I know I can't use 16's on a regular basis anymore because I don't want to mess up my wrist. But what I do know is I now have a secret weapon in my bag if I need it for a game or two.
