Well yeah. I think people would prefer if the courses were hard enough that no one would even suggest smaller bikes as an option.And then the rider on the DH bike inevitably wins.
Remember when Graves got 3rd at the World Champs on a SB66? Thats scarily close to having the World Downhill Champs won on an Enduro bike. And as someone who has spent a lot of money a 200mm front and rear DH bike just so I can turn my nose up at Enduro weaklings, I won't stand for a course that lets them have anything resembling a chance. Any time I get beaten by a fitter, better rider on a smaller travel bike I'm hereby declaring that the trail was just too easy and didn't suit someone as gnarly as me.
