2600 Kv rated motors? which one?

[Revracer]

maxamps 5000 lipo. thats what i will run on 3s right now. and later on i will probly get twin 5000 2s to run in it if i go that high. i already have the 3s. and i will be running 2speed and mech brake. and a 9l is rated for 2700kv(around that) so it would probly run a little cooler, slower, and have more acceleration than the 8l right? or should i just get the 8l? since you say the 7xl wont be able to turn fast enough on a 3s... that disapoints me. squee said he runs a 3s and 7xl and it does good.
