Had a very nice ride this morning--on my Christmas present KHS 650b Team. Friends rode by to scoop me up and we hit the local trails early. I was worried about the steep and rough stuff on the hardtail with "only" 120mm of travel up front (coming from a dual suspension), but I was pleasantly surprised. The bike felt great under me. The 27.5 wheels felt like they rolled over stuff a bit easier than my 26 did, and it felt easy to flick around--and it's light! I really wanted a Niner, but this bike really feels like it's "just right." More ride reports/pics to come!
