which is more stable and better over jumps and rough stuff, b3 or XXX (please help)

[stormperson]

i am racing at big boys toys in fall river, MA, and i wanted to get a buggy. which is better on short tracks, with some rough stuff and alot of jumps? the xxx or the b3? they are pretty much split their on who runs what. however the losi's are a little bit more prominent.

i already have a xxxt, which i like, but the price of a xxx is comberable to a much upgraded b3.

are they both prettymuch the same stability wise?
please help!
