Yes it is pointless! 650b in the gravity feed mtb, is going to as unsuceccful as 29'er DH bikes were, personally I have not seen a single 29er DH Bike on a bike park or DH race! , for all the metro out there! men up, one more time it have been said, to hit a big jump, go fast, or rip it the only thing that you have to have bigger is your balls! Coclusion, you can buy a bigger wheel size, but no riding skills, also if you are afraid of an small jump or gap, in stead...
