1/2" ivory ferrules...
i played a couple of games with john showman's playing cue down in florida the last time i was down that way. he has 1/2" or shorter ivory ferrules on his cue, they seemed really stable, but it was not used to break with. the short ferrules seemed hard to get used to, at least for me. i felt like i was almost ready to foul the cueball during setup and practice stokes, i guess just an optical illusion because it feels like you are getting way to close to the CB, and i actually did a couple of times...JS
