I'm the the full-finger minority as well, & I've been having somewhat of the same issue. I haven't been out since it hit mid-90's in GA yet, but I'm supposed to go with a friend tomorrow so I'll see how my gloves do. I just wear a cheap pair of Performance-brand full-singer gloves that I got on sale for $15. They've served me very well so far though. I'll update after my ride tomorrow with how well they do in 95 degree, 90% humidity.
