I haven't gone through this thread but I was wondering how this buggy stacks up against the 22-4? I owe the 22-4 and really like the way it handles. But, I am over the constant diff ball changes with this buggy as it isn't the easiest to always change them. Just wanted to see your guys thoughts about the two buggies. Also, does anyone know of a possibly new HB 4wd buggy? thanks!
