Speed will carry you over roots and rocks as well, but you have to be aware of the surface if you're turning or braking. My riding buddy has been talking about getting a GoPro camera. I would be nice to show the local rides as every locale has its differences. Our trails are almost as lush and rooty as yours in the PNW but rockier with a fair amount of mud, while up in NH and Me its a lot rockier but sandier. We don't really do much downhill stuff, sticking more to trails with some balance in descents and climbs.
Different stuff from all over ...
