Glocke; another thing to consider.  The distance to that first fret is significantly affected by the body style.  With a standard point body the first fret is further away than with say a Rogue body.

Going back to the original question (scale and model), here's how I chose:
 
1) The scale length was simple for me, I already play a 34 scale and like it.
2) The model choice was simple, too:
 
It had to be coco bolo, so the most affordable option was a Mark King Signature Deluxe.
 
As to all the other stuff (bookmatching, carved headstock, gold hardware, etc), I basically spent way too much time surfing the Factory to Customer threads on the Alembic Club.  This gave me good ideas about what I really *needed* to have (coco bolo, ebony lams) and some nuce stuff, too (like the carved headstock, that I'd've never thought of on my own).
