Feigao XL can in a slash??

Well, i'am looking for a new motor for my slash. I've burn my 10L today, maybe by some sand go in the can were the wire goes out of the endbell.
My question is: What do you think about an "XL" can in the slash??
A 6XL or 7XL, on 11.1 volts i know that's realy to big for a slash, but i think that this motor will be happy to be in a very light truck.
Never need to worried about temps of gearing.

What do you think!
