Been playing with my Schon for 23 years now and it plays as good today as it did when purchased in '91. It's been refinished once (by Schon), and I have 3 different shafts for it, one is a new factory shaft from Schon I purchased and had fitted when it was refinished a little over a year ago. The other two are original and play as good as the new one if not better. Have played through various stages of cue tips over the years including Schon factory tips, triangle tips, lepro, moori, and currently use sniper tips. The cue itself has played very consistently throughout, with the only change being in the play of the tips.
After all these years, I still find it to be one of the best hitting and balanced cues I've ever played with. Take care of your cue and if it's well made it will last you a very long time. That's just my personal experience and opinion on it.
