nike makes the best blades. the nike thesauras or the nike chipper will do you just fine. the chipper has a 5 inch soul plae and a 4 inch negative plate with a 5x5 inch h block. the wheels are made of fiber so you should be good to go.
now if its speed your looking for, rossignol makes an incredible indurance blade called the bleth? its it has a rock-steady lemon scented outer shell that is great for down turns and whip thops. if your going for that shat-natty 3 off the west curb, get the mass.
