i went in to Valley Forge this year determined to get a better cue, and based on a lot of research, was pretty sure it would be an OB-1, Predator QR2 or Sneaky, or Lucasi Hybrid, and 75% sure i'd want the OB. i visited each booth and tested the cues, waited an hour, and then tested them in a different order.
to my surprise, i couldn't handle the ferrule on the OB, despite having read about some peoples' objections to it and thinking "well, that won't bother Me". something about that and maybe the taper just made the front of the cue look blunt and weird.
i liked both the 314-2 and the Lucasi Hybrid, and ended up picking the Lucasi, partly because it just felt better (maybe more familiar), but also partly because given the deals i could get at the show, it was a much better buy (the only Predator Sneaky available was a steel joint that was a Very beatup demo).
i'm now 2nd-guessing that decision. as McChen says, i've discovered that the deflection on the Lucasi Hybrid, while less than a standard shaft, is significant. so i'm thinking of ordering a Predator Sneaky for a longer experiment, even though the new ones are supposed to come out in 2 months.
on the other hand, Thorsten seems to do ok with the Lucasi... his is the standard hybrid shaft, but turned down to either 12.2mm (according to him) or 12.4 mm (according to Lucasi staff). of course, he'd probably run a hundred with the bumper end.
as a sidelight: does ANY pro really use the skinny shafts from Predator/OB/Lucasi? Darren, Ralf, Scmidt (when he used OB), and most of the others i follow (admittedly, the ones who play 14.1) all seem to use the regular shafts, not the skinnies.
