I know for a fact the short A3, Echo Team and lite frames are lush riding frames. I have ridden all of them and they feel really nice. I have a long A3, then rode a short A3 and wish I had got one of those, but I still like my long A3 anyway. Rode a long Czar and didn't like it. Don't know if it had to do with the length or the feel of the whole bike. Also, it was quite heavy for some reason.
