Well, I use a RD at work, a BS on my "main" computer, and cherry reds on my other computer. Since all see a lot of use, I am able to switch back and forth pretty easily. Keep in mind, though that I also switch between QWERTY and Dvorak. I'm getting pretty good at it, though I only use Dvorak while standing, so it is pretty easy to change in my mind. Standing while typing means Dvorak. Sitting while typing means QWERTY.
How long have you had your keyboards? it took my a bit to get fully acclimated to it, though I don't know if my testimonial is really worthwhile, as I still don't type properly on either.
