Many people who drive around brushless trucks do wheelies because they can/enjoy doing it. If this isn't for you, then a center diff is for you. In my Revo I'm running a 1/8 center diff with 30k oil, and using it diffs out to the front, but occasionally I'll get a bit of a wheelie. Of course, the instant power can be tamed through settings on the speed control (depending on the speed control), so it's not at all hard to keep the front tires on the ground at all times.
