delrin vs. intetegral tenon
I'm sure this topic has been discussed in previous posts but I'm not able to find it. I have noticed that most high grade pipes have integral tenons. Delrin seems to be very strong, and it's self lubricating property makes for a smooth fitting tenon. Is there some drawback to delrin tenons that I'm not aware of? I don't see many makers who use a delrin mortise sleeve, is there a disadvantage? I have the necessary equipment but delrin is so fast and easy. Should I start turning my tenons?

The major criticism that usually arises when delrin tenons are discussed is that it removes the "weak point" in a pipe's construction. So instead of a pipe falling and breaking the tenon off in the mortise--an easy fix for a trained repair man--the pipe will supposedly fall and shatter the shank. Usually what happens, though, is that the pipe falls and you can pick it back up and smoke it instead of having to send it off for repairs. I wouldn't start turning tenons if I were you, but it's certainly just a matter of preference.

Another advantage of Delrin (my experience is with ABS - very similar properties) is that it has more "give" than ebonite, etc. You can turn it a smidgen oversize and still get an excellent fit, whereas ebonite has to be pretty much spot-on tenon to mortise size. There's also less chance of the "loose tenon" problem that ebonite/vulcanite tends to exhibit later on.
