How can a joint that can take full force carom shots and masses not stand up to a break shot with the smaller, lighter pool ball? If it can't there is either a quality problem with the cue or something really unusual with the break stroke, like hitting the table or something. I don't see how hitting a pool ball with a wood joint would hurt it. Wear or fragility while not hitting balls might be another matter. But maybe I am wrong. I have a couple wood joint cues with both pool and billiard shafts, but don't play with them much so I don't see the wear and tear really. I just can't envision how a wood joint would bust by hitting a ball with it. If the shaft were bent into the cloth I would expect that to give well before the joint. I play mostly all pool now and have decided I prefer a more standard pool cue for that. The wood joint has its own feel and such tho.
To the OP, not many makers do these joints, but there are some advantages. Check out Ron Kilby's website for more details. Dieckman's too.
