Anyone used both? Better yet anyone know what the mugen ones weigh, 1.71grams maybe like the xray's? I've always used the Xray shoes, and really like them. I shave down my clutchbell every 1/2 gallon of fuel but the shoes still only last about 1.5 gallons (~3 races). I can get the Mugen lightweight shoes for a good price, are they comparable? Would I notice the difference if I switched?
