I've heard that the more flex in the bar, the less arm pump, more forgiveness on rough landings. Opinions on Pro-Taper VS Renthal? I thought everyone was going away from the standard bar (with the cross bar/pad) because they are too rigid. Anyone use or have knowledge on Flexbars (i think thats what they are called). The bars that have a hinge and are spring loaded, fairly popular for the quad guys I believe.
