I really is a sweet experiance to ride a hardtail. The hardtails you ride are more DJ-ish, so this has the geo of an AM frame I guess, the top tube is higher and a 67 HTA. I use it for hardtail downhilling from time to time, some non-DJ style jump/doubles, mostly drops, dramatic improvement on my skill level when switching back to the fully, as you can imagine.

 actually, I ride a freeride/AM hardtail as well, I hate DJ bikes...

 Yeah I just realized, the duncon cocker (or one of the hardtails you have) is like a FR bike not a DJ. You'd break a DJ bike either way, light and nimble frames + you + utah would not be a good combination
