I use Colemak DH, and have done for a few years. I could never touch type very well on QWERTY anyway so using QWERTY I am no slower than I was originally (in fact, I'm probably faster, since I now use my fingers properly). As long as it isn't very frequent, using hunt-and-peck on any QWERTY keyboards you come across is fine, and touch typing a different layout won't affect it.
