I'm quite impressed by the Vigilante myself. It doesn't seem as "crash test" resistant as the Xmaxx, but I am quite confident I would have a good time with it. I'm a ways off on buying another 8s rig ATM, also pretty content with my Xmaxx and K8S. They each have different traits that I enjoy them both for.. the Vigilante seems to fall right in the middle between them I feel. Pretty resilient and forgiving, like the X, and pretty stable handling for it's size, similar to a K8S or O8S..That was pretty awesome! Really not that much carnage. I would buy one if I had the space to run it.
I also agree about space limitations. The Xmaxx is pretty comfortable in small spaces, the Kraton 8s, not so much. It definitely needs more space to strut.
