For effs sakes, Ride whatever you feel the need to, in the end its the rider that makes the difference, not the bike. For refference I will point you to Thomas Genon (google him) who won the Red Bull Joyride on a single speed hardtail dj bike with 100mm up front, where the rest of the field was filled mostly with 120mm plus dual sus bikes. <Point made> Feel Free to discuss amongst yourselves
