For all the MTBrs, good value?

From what I've ridden of the south downs if you ride full suspension there will be nothing to challenge you and develop your skills. Good brakes are more important in my opinion than suspension. Currently I find my brakes the limiting factor in my speed off road downhill 90% of the time on the South downs riding ridgid. There are sections I could ride faster but don't because I can't brake for corners e.t.c further down because my brakes are less one finger lockup more three finger slight deceleration.

isn't the limiting factor is the type of gravel than the brake?
