I have average sized hands, but prefer 19-20mm spacing. I think the main reason is that I played four string for over two decades before switching to five, so my plucking hand became accustomed to the common Fender-style four string spacings.
Much as I'd love to own a MusicMan SR5, I just can't deal with the narrow spacing (and trust me, I've tried). I'm not even much of a slapper; narrow doesn't work for me with any technique. I had an 18mm Lull for awhile, and while I found it playable, I never got completely comfy on it.
I suppose if I completely immersed myself in a narrower spacing I could adjust... but why? There are enough great choices with 19mm spacing, no need to even consider torturing myself.
