I had to weaken mine considerably to get it to work on my league pattern/surface: 5.5 x 3.5, pin over center of the bridge. Still, it can hook a lot or I can rocket it for a smaller hook. Due to wet/dry nature of our oil pattern, I have to put it away somewhere in the 2nd game. Had some very nice 1st games with it. Not your every day ball without a good deal of oil.
