I have ridden them and they are better than you might expect. They have great power once uncorked, about 50 at the rear wheel. The suspension is very well tuned for high speed riding and gives a feeling of confidence. The bike masks it's weight very well.
One of the nice things about that bike is that it does not deflect from it's course at speed. That makes it an easy bike to ride fast. I have not tried one in the tight stuff, however I suspect that it will be fairly good in the tight stuff too. It really feels like a well rounded bike.
The only downside to the bike is that it is a big bike and fits bigger riders best.
BTW I am well over 200 pounds, 5 foot 11 and would consider myself a bigger rider due to size and weight if not height.
