I just got a cue where the butt is 28.25" and the shaft is 29". Everything looks original and is say the cue is from the 70's-80's. The joint is .875, 1.06 above the wrap, 1.20 below and 1.26 at the buttcap. Are these shorter butt cues built with billiard cues in mind? All my other 57" or 57.5" cues are all split evenly.
