Under the cuff is better or no?
Let me put it this way=
Practically all over the cuff gloves fit all jackets
Not all under cuff gloves fit all jackets
It's not a terrible thing because my midlayer has thumb loops so I am not getting anything on my skin but I prefer the over the cuff for the extra bit.
With what you have said about your hands, I would suggest some mittens. The only mittens they have on evo are the Gore Tex mittens for women but I don't see what the difference is.... They are all black so I'm sure they could pass plus it's not like anyone gives a shit. They are a similar 3-1 system to the Burton GTX gloves I have. On backcountry.com there are some POW Gloves Warner GTX mittens as well.
