well i did it. had original 190mm and decided to go with 200. not that much different from 190 although it's a bit stiffer on the turns. other than that it looks great. went with Shinko R005. spoke with service guy today and he said 180-190 is okay but 200 is pushing it. i guess ill have to live with it until it wears out. anyone else running 200 on a blade?
