No problem about length. You may pick up not squeezing faster than you think. It almost sounds like, though, that your thumb pitch has been changed to forward, then almost any squeeze would cause it to hang. I cheat my thumbhole, though. It's purposely large so I can put a piece of magic carpet in the back and tape in the front until I like the fit. My thumb usually shrinks as the night goes on, so I'll add more tape.
