Guys - I have an HPI RS4 3 EVO+ and I like the HPI brand a lot! Its getting cold and crappy outside but I'd still like to play on the driveway. I am looking for something to bash around my very large yard with. It has tons of hills and tons of open grass which we keep ~ 1.5 - 2" long max. I am looking for something that will be the most fun and these two models look like good solutions. I like the MT2 because its 4wd and is basically an RS4 with upgraded parts/lifted parts. I like the Firestorm because its pretty bad ass and RWD would be kind of crazy in some light snow or gravel/dirt. But... what do you guys think? They're not that different in price, but both have pros and cons. I like the 4WD as its probably most controllable and would do best in the snow... but maybe it'd be cool to have a RWD in the snow and be all over the place...

Help!
