I still have several of those blanks around my shop that I never put out. I sold the blanks joined that way several years ago. I heard of very few problems and the ones I did hear of sounded more like customer abuse. Like the cue breaking at the joint. That joint never causes any buzzes like a screw and tenon will occasionally have. It was strong and seemed no more prone to warping than any other normal method. So you might ask why I don't use it in all my cues. Two main reasons are: #1 I like the decorative rings at the wrap joint and butt sleeve. #2 if I can't have rings there I want the butt and forearm woods to match or have full spice points. So mainly it is a looks thing. All the ones I built had exotic woods in the handle area and birdseye in the forearm. There seems to be an overall negative attitude when the finger joint is brought up on here. But I have yet to see any real good reasons it is a bad way to join a cue. I have not done it in many years, but still think it is about as good as most any other method.
