I personally Like Hpi. I own a hpi nitro mt and the thing is great! The only downer to hpi is that the 15 fe runs hot so think of a new engine down the road.. Trust me it turns the car from zero to hero! I dont know about the ss or the super nirto but i bet the Pro 3 would give you the speed' you want. I've played with one and its great. Dont think that team associated cars are bad but they are also Really good cars on the market. I'd say stay away from kyosho, good cars, parts are hard to get.! good luck
