Used it on beans,2500acres that ran 42-45 bu and could cut 3.8-4.7 depending on humidity. The draper constantly feeds the machine and their is no little bunches coming in, thus smoothing out the feed. You do not need fieldtracker for this header as it has it's own unique suspension that lets it give an incredible float. Have not used it on wheat,but have seen others with draapers and they like them. Flex drapers are too new to talk about how they hold up,but other draper heads seem to wear real good.
