One shaft.... I have a pretty good idea of what you want, but if you have any specifics let me know.
Out of the ebony/bem cues you posted, that Dufferin on the far right caught my eye.
I will add for clarity.
I would really be into a traditional 5/16 x 14 piloted joint at 0.840
Stainless is cool, imitation ivory is cool. I dig the way Sly does it. I will consider ivory but I am really careful about that.
If a Joss/Stroud/Scruggs shaft fits that's excellent. Plain black collar is excellent.
I do love dashed rings so I might be sold on that, especially if matched to the old Joss diamond catalog dashed rings.
Basically a plain jet black ebony into BEM. Full or half splice. If half splice, black wrap. I do dig an old school Delrin butt cap.
Definitely no kind of ring at the A joint.
There are variations I might like. Key thing is it must fit the collection I posted.
