Thank you! Wow I also didn't know that you weren't allowed to break down your cue and use your shaft to jump either. That really sucks, who the heck jumps with a full playing cue? It's very uncomfortable and hard to control due to the weight.
You can now jump with your break cue as long as it isn't phenolic. We had regionals this weekend as the rule on jumping has changed. Jumping with a full length break cue isn't that hard just a bit awkward if your cue is heavy
