I used predator shafts for a few years, then tried the Jacoby at the SBE a few years ago. Ordered one on the spot (I play with a Jacoby, cursed myself for not ordering the cue with that shaft in the first place). I decided to go with a middle-ground approach and had it tapered to 12.25mm. I can pick up a 314-2 and play with no adjustment necessary, but my Hybrid shaft just flat-out performs better and gives better feedback. Anything I get in the future will have an accompanying Jacoby shaft to go with it.
