i'm using LD shaft from Predator from 2008 until now. But in 2009, most times I switched to my "not so LD" one piece shaft. Theres a advantage and disadvantage using both type of shaft, IMO the feel is more better using a one piece shaft and more better using with 1-2 tip of high english (even draw sometimes on smaller diameter is not produce much spin as a 314). In other side IMO LD shaft (splice shaft like a pred) is more accurate when using english, but it is not so low deflect when using high english.
Some guy using a high one because it's become a nature to them to compensate, and that type of guy IMO is the best one to use any cue (throw any cue and look that they capable to switch very easily). But my little brother (who play with LD shaft since the beginning) is rising very quickly, because he doesn't bother to compensate a lot when using english. But he is just good to draw, but sometimes missed when using high and if he doesn't use his cue, he is like drop 3 level of play.
IMO some deflection is good but not too many, using a Hybrid Pro 2 or WD 700 (LD production shaft) is giving more feel for me, unless you have a custom cue maker to make you one.
About the predator jump, it help me a lot to teach some people to jump, but not the best one around (in my country).
