I have a newer schon, plays great. First thing I did was toss the shaft aside, and throw on a jacoby v4. That took it exactly where I wanted it to be.
The bottom line is, if you think a cue plays like crap in general, change the shaft and tip. The butt has almost nothing to do with the stiffness of the hit. It has a lot to do with the "feel" and the sound, but a whippy shaft is a whippy shaft, a stiff shaft is stiff.
Best player in one of my leagues plays with a shaft that costs 4x as much as he paid for the butt of his cue.
I play with a Schon because they're local to me and I want to support local makers. I also got a smoking deal from the good guys at Schon, which helps.
My main playing cue is a custom cue I built for myself, because nothing beats a tailored cue.
