I've been using an old blue thunder I got recently. It has very low games on it and I love it, but sometimes the center puts out too much oil for it to handle. ( old, un-reliable oiling machine that needs to be repaired or replaced )
I can usually play with my feet on 28-30, targeting third arrow and have the ball react well and end up in the pocket area, but just Thursday night I lined up in my usual spot and hit the 3-6. Moved my feet right and still hit the 3, so I moved a bit more, found the dry, and watched the ball race brooklyn on me.
I could never find the adjustment. It seemed very elusive to me. I think if I had a ball that handled more oil than the old blue thunder, I could have gone to it and still played close to what is my "normal" shot.
