How fast can you go on this board with randal trucks without getting speed wobles???
Surprisingly fast actually. It's not so much the trucks as the bushings you put in them. If you want to use them for serious DH then you need to swap the bushings out for stiffer barrel shaped race bushings (recommended anyway). Also, grippy race wheels would be a good idea. You can change the way you tighten the trucks as well to add stability if you've decided you're gonna run maryhill or something.
