I've got a Doug Elliott mouthpiece that I really like but I also prefer the feel of steel due to some minor alergic reactions to silver and gold plated mouthpieces. And lexan didn't sound the same  I recently discovered Parker mouthpieces and I'm wondering, do they fit the XT series rim threads? Have anyone ever tried that?

I've never done that personally but if they can do threads, they are presumably capable of putting Doug's threads on there if you have a cup to send them.  You could also get a used steel or titanium mouthpiece and have someone thread the rim for the underpart.  Osmun does the best steel/titanium threading in my experience (well, Doug threaded one for me awhile ago and broke a billion dollars worth of tools; the threads were amazing but unless he's changed his mind about doing steel...  ). They recently threaded a titanium G&W for me and it had a quick turn around time and the threads seem to be properly centered. (I've had some steel ones that were not).
