Hey, I have been using Colemak DHm ANSI for a little less than 22 months now and have been very pleased with it. I learnt today that I was using the WRONG layout with the bottom row being ZXCDVKH instead of the supposed XCDVZKH. This has been very comfortable so far and I have not really felt the need to "curl" in. This is also comfortable because of its proximity to QWERTY considering I sometimes have to use QWERTY at college. However, are there any specific reasons for which I might consider switching to the latter layout? By the way, is there some name for the former variant?
