i have several shafts from different cues. my all time fav is the universal smart shaft. i can always go back to it when im off and find my grove. i grew up on a meucci, have a couple of 314 1 and 2 dont really care for them. currently i shoot with an tight grain sly. also the ob-1 isnt bad, i have one for my sly. i mix it up from time to time, but i ALWAYS have my old Mcd with the USS in the case, never fails.
