What are you using the truggy for? Bashing, speed runs or racing? If it's racing The 60mm Medusa would even do. Mike was running a 60mm Medusa in his E-REVO last I heard and thats not a light truck either. For bashing or a mix of everything the 70mm would prolly be a better bet, but for all out speed runs while maintaining good temps go with the 80mm. As Arct1k said the CC/neus will be close to the same price but currently the best bang for your buck goes to Medusa. I've had no stripped threads on my Medusa, choose the proper length screw, apply a drop of loktite, and tighten down. No need to put a 4' pipe on the end of the allen wrench
