1st generation 314's play a lot like solid maple shafts, they have a great hit and feel that you can't get from any other low deflection shaft that I've seen.
I have 314 shafts 1 st gen for every cue I own. Love them. Yes they are getting hard to find, most of them you find will be worn, and well used, it's hard to find a nice, clean, barely used old 314. If u find one, grab it, it'll cost you 150-200.
