RE: GENESIS or NEMESIS?
Sounds like you're doing some heavy bashing. I don't order many parts for my Genesis but I'm not jumping off buildings either. Personally I would go with the Nemesis if I were pick from the two now. The Genesis is a great truck and I've had it for a year now, but I did spend the money to upgrade the transmission to the Nemesis just because the braking system on the Genesis sucked. Now with the Nemesis brakes I had to make adjustments to keep it from flipping itself over. So I along with the transmission, I had to buy dogbones, differentials for the front and rear, and bulkheads.
I'd suggest the Nemesis, others might think different.
