Hal, I forgot to answer the last time you asked me this question. For lack of shaft technology lingo, I'll explain it in my terminology. I feel like this shaft puts an unusally large amount of spin on the ball when I'm NOT expecting it.For example: On a long straight in shot when I'm looking to just stop the cue ball, it seems that if you do not hit the absolute center of the cue ball, you will get spin of some sort on the shot. I'm sure I don't have a straight stroke and my eyes might not be so great anymore, but after playing with a Bender for a long time, the way I would describe the hit is that it has "give".Whereas the Bender was very stiff. Maybe this is the wrong terminology. I don't know how else to describe it. On a bar table, you can get away with alittle spin but not on a 9 footer. Feel free to explain in technical terms what it is I am experiencing with my Predator. Thanks
