Weight of the truck, driving needs and cell count are all deciding factors, as well as terrain and tires. Most go with the 9L, as it runs very well on 12 cells and can be juiced up to 14 cells for more power. The Lehner xl motors (2800 or 3100) also work very well for these vehicles. the 9L is a much more viable option when the motor clamp/heat sink comes into play, because the fear of popping the can is eliminated.
