While I am no big-air style guy by any means, I pretty much ride my SS on everything I come across. Maybe a bit slower down the rocky tech stuff than I would if I had suspension, but I can usually keep the FS guys in sight on most of the reasonably rocky downhills, unless they are REALLY good, or really crazy! I like the feel of rigid for the precise control and steering feel, but also because it makes me slow down a bit for the nastier sections. Keeps my speed to a more reasonable level if I should unload! That said, there are a few times here and there when I am skittering the front wheel through a bumpy turn that I think a bouncy fork might be nice! I agree with the other "old guys" here that "All Mountain" is pretty much old-school XC/Trail riding. Maybe a bit bigger with some of the advancements in suspension and frame materials, but still the same thing concept-wise. I consider myself a "trail rider" and that can be smooth or buff, steep and rocky or anywhere in between. If I can't ride up it, I push up it (SS or gears) and I ride down anything I think I can, and if for some reason I choose not to ride it, then I get down it however I must and keep on riding. The best trails always have some section that I can't ride - or always get part of one time and don't make another!
