tried out my 20 inch sand stars this weekend in glamis, i was loving them..had them @ about 6psi...wow.. big difference compared to those cheesy ass geckos i use to run....Also nobody could get me on the launch @ olds...i was pretty impressed, i was getting my buddy on launches, he was running 8 inch haulers...im thinking he just needs more practice with those..But im happy overall....the only thing i did notice is couldn't roost very easily, ima try lowering the pressure a bit next trip...
