Hi, I just got started with the Kinesis advantage the other day, and started learning colemak while I'm at it.
The one problem I foresee is regarding the size of my hands, which are quite large, so my palms are only partially supported and the rest of my arms are floating, since the kinesis is relatively high. I'm considering buying a keyboard wrist rest for extra support, which could support my palm and consequently the wrists. However, I've read that these can be un-ergonomic for the wrists (ergonomics is the whole reason I'm making the switch). Any thoughts or recommendations?
