Of course if you don't sell the Cat, you've still got a 4wd too. Only downside in that is the the wheel fitments are different, so they need different tyres.

I actually think Matts wrong about the Cat - indoors on the carpet its great. But when we go back outside I think you'll prefer a B4. Certainly, though I never really liked mine, it was nicer round Goshen than the Cat.

You'll be needing a different motor for a B4 though, the Losi you have now is a bit quick for a 2wd.
