I used to gig with a guy (Ken Hays of Paris, Illinois) who used a .17 for the high e on a lovely Koontz archtop. There wasn't a whole lot of bending going on, but the sound was pure smooth jazz all the way. This is the same guy who plays rock gigs with a Howard Roberts Fusion (archtop) with a scalloped fingerboard, and just kills with it through a pair of Boogies.
