I've had three D models and seen countless others (C and D models and later, more modern models) and all were flat-faced wood-wood...even the "stainless" joints were flat-faced wood-wood with a stainless sleeve. The hit is very nice. Solid, with lots of feed back ("good" vibration). I prefer an old school 5/16 X 14 piloted stainless joint myself, but that's really just a personal thing. I have nothing against the McDermott style joint and still enjoy shooting with them. I never saw a problem with the wood threads in the shafts (my jump/break is a McDermott, no issues, there, either); they hold up very well, even after decades of constant use. The only problem I ever saw was the early D models would suffer a little bubbling in the laminated rings on the shaft's joint, but that got corrected in later models (and of course, McDermott fixed those that did under warranty at the time). A lot of top custom makers prefer to put out a flat-faced wood-wood joint similar to McDermott's cues.
