I've tried the cut Blade brake and I didn't care for it. But lately I've been cutting my Pro Model brakes.
Reason being, because I was sick of bailing and the fender bending/widening. I cut it just far enough so that my heel doesn't touch the wheel, but it won't bend or widen if I bail the scooter onto the fender. I also be sure to round the edges do that it basically looks stock. Because if you don't it looks ridiculous.
