Keep practicing! When I switched to KA2 I could not type with the same speed for months. I've also decided to switch from QWERTY to Colemak at the same time - it did not improve the situation.
But I am fine now, have a KA2 @work, Model 100 @home and have no problems switching between them whatsoever on a daily basis. I've also ordered Glove80 and I am sure it will be fine. What I have some problems with, are those rare occasions where I travel and have to use my notebook's keyboard. Everything - staggered layout, lack of thumb cluster, no split, scissor switches - is just a source of huge discomfort.
