To get any kind of speed out of the 9XL on 3s, you're gonna have to gear up quite a bit and that's gonna draw as much current as running a properly geared 7XL.

Even though you don't wanna hear it, the 9XL would work better on 4s geared right. You could still use the MM cutoff, but you'd need to get a different lipo pack.

If you stay with 3s, I would get the 7XL and try not to gear too high to keep current draw down. Even so, I would run two 3s packs in parallel to increase the current rating.
