Jammin X-1 CRT motor selection

Sorry, I wasn't yelling, just wanted to make my intentions clear. So will the 7XL be a good choice? (on 4s) I dont have to hit 50, just want a truck that is pretty fast. I have a stampede with a mamba max 5700 on 3s now and I love the power and speed it has. I'm assuming the truggy will not come close to that kind of power/ weight ratio though. If the 7XL will keep cool, give decent runtimes and speed it will be enough to hold me until I get the monster max.
