Good stuff! I'm a little surprised that you found the hand compartment tight, as general consensus (and personal experience) seems to point to the Twins as having a medium-sized hand compartment (the Top Kings are crazy tight LOL; for the record, I have long and wide but thin hands, if that makes any sense). Smart move on shifting the wrapping focus to your wrists as the Twins' cuff is indeed shorter than most other gloves' -- when you clinch, the advantage it offers should become readily apparent.
I also agree about the thumb position; I like it too!
Just a small tangential question: you picked up a pair of the 2013 model, right? The ones with the black and red label (as opposed to the older models with the white and blue). There are some minor differences in the two models.
Anyway, enjoy your new gloves! Once they break in, they'll feel even better!
