Bob is, of course, exactly correct. IMO, some cuemakers build a unique joint for their cues to encourage future shaft support be directed to them. Not an unreasonable marketing practice, but, beyond being "unique," such joints do not materially add to the performance of the cue.I think that with two sets of threads the problem is to get the force evenly shared between the two. I think that's very hard to produce in practice. The set that's more securely anchored is going to end up with most of the load and the other set will just be along for the ride.
