Sprint = good for collectors and Spydienuts
regular production = better for people who want an EDC, or a user
Being completely uninformed, I'd think it would make more business sense to put a carbon fiber in regular production. It would be more available and, IMHO, a better seller.
I'd also like to see a high end gents folder or smaller knife - all of the carbon fiber I've seen is pretty slick, not what I'd want in a working knife. Granted, this would put it in direct competition with lots of other stuff out there, but that might not be a bad thing.
YMMV
