Rode a set and they are amazing but got afew ideas to put across. I suggest you have the option of flanges on the scale grips. 90% of people cut them off anyway but not all people hate flanges. I love them. They seperate my thumb from my hand allowing for easier barspins, I ride with my thumb over the flange and its a huge preferance for me, I wouldn't buy a set of prips if they didn't have flanges.....
And also, plastic barends are crap, it'd be lovely if you could make them outta metal,m just sayin
