Pechauer P23-F

Hi, I'm new here and new to pool and bought my first cue, a new Pechauer P23-F. (Strange cause it's a 2012-14 model, but it's new allright.) I was wondering what shafts would fit on the Pechauer PRO speed joint, cause I'm looking into a carbon shaft from Go or Becue.
thnx.

I know, but they are hard to come by in Europe and cost 499 euro with the standard tip. The GO-SL shaft is 399 and the Becue is 419 euro. Ofcours you'll say what's a hundred bucks….true..
