I have a 2200kv puller pro in my ax-10 "comp rig" and am a big fan. If you ask me, the 2200kv is a great motor.(of course I am biased here but...) I have under-drive gears in both front and rear on my rig and beat the crap out of it and have never had any overheating issues. It's got real nice low end torque too. If you want to sacrifice a little low end for more wheel speed go for a higher kv. None of the motors you mentioned should have any issues with the setups you listed.

Between 1400 and 2700imo. More people that win tend to stay in the lower range, between 1400 and 2200. 2700 and higher is what I run on trail rigs.
