I've also got the Burton Impacts, as well as Burton RPM and Defcon Man In Black. I've got a thing for animal hide :/
I'd definitely recommend springing for the Impacts because a) the wrist protection is excellent b) the palm is rugged c) they are quite waterproof d) they're the warmest gloves I've work. They do have a break-in period though, 2 or 3 sessions. I got mine on sale for $26.00 so look around, they're worth every penny for the peace of mind alone.
