Right now I'am on my second Predator 314-2 shaft. The reason I got the second one is because the first one developed a slight wobble. Some might call it a taper roll. Well after playing with the second shaft for around 4 months it has developed the same wobble. My question is this normal? If so then why? My Mezz WX700 is dead straight. Also both my OB-1+ and OB-Classic+ are dead straight. Why can't Predator make it so they straight like when I first got them. Again is this normal or am I doing something wrong. After I finish playing I always put my cues away in there cases. I never leave them leaned on a wall or laying on the table. Thanks, Michael
