i'm a bad mechanic so V brakes are good for me.
I never understood this obsession with brakes. I think it is dangerous to go down a mountain side at 35 mph (or more) with a loaded bike. There might me a muffler in the road. Dodging it at high speeds is a good way to end your bike, camping trip. You shouldn't be going fast downhill. The brake type on your bike is irrelevant.
