Now that I have most all the popular necks that most on this forum have been using I have what I think might be helpful.
These necks were all test played on a Ref 54 tenor.
Ref 54 neck. I found that this offered the best intonation, full tone into the upper register, not the most free blowing, it's a little more work to get the high notes to pop. Overall tone is kind of dark.
Ref 36 neck. Very similar to the Ref 54 only a little clearer sounding and a bit more work in the upper register. I have two ref 36 necks and have found that some play stuffy and some are freer on the upper end.
Series III neck. The Ferrari of the selmer necks. It's noticeably brighter, much easier altissimo, intonation is surprisingly good on a Ref 54 tenor. I did find that there is a shrill quality in the upper register that could be annoying in a recording studio, but for being able to fly around the horn this neck is one of the easiest that selmer has to offer. Over all a brighter neck that offers a fast response.
Barone. Mine is a Bronze neck. I found that the tone is fatter than a selmer neck, but intonation can be a problem especially in the middle register. Altissimo really isn't all that impressive as this neck is described as being a larger bore, but the aperture actually measures (as small)smaller than the Selmer necks, the neck does flare out more where it meets the tenon however. I'm not blown away by this neck as I felt the altissimo was a bit mousy and some of the high notes like the G where a straight up b**ch to hit consistently and get a decent volume. I found this neck didn't completely take away the selmer sound, but it's not an american sound either. It will get the job done and I think the palm keys sound fatter than with any of the selmer necks, so work your butt off for those high notes and clean up the intonation and you might have something you like.
Peter Ponzol Gold Plated Brass. Very fat sound, fatter than any of the other necks in the upper register. Effortless altissimo(or as effortless as you can get), intonation however is a bit screwy as you need to pay attention in the middle register and especially in the palm keys. I would describe the sound you get with this neck as buttery and thick on a Ref horn. It has the largest opening at the aperture. You will totally lose the Selmer core with this neck.
Ref necks are low arch necks.
The Selmer III and Barone side by side are very similar as far as arch and shape, they are high arched, but not as high as the Ponzol. The Barone is a hair lower arched than the III, but not by much. The Barone does seem to have a larger bore towards the tenon, but the apertures of the III and Barone are about the same size.
The Ponzol is a very high arch neck and thus shorter than the others.
Apertures for all these necks were .507-.510
The Ponzol aperture however came in at a whopping .517. (measurement amended see post below).
All these necks were played on a Ref 54 tenor with a Mojo NY Link .105 and RJS 3M reeds.
