if you are going to do rock climbing get a clod buster, jugg 2 or txt-1. there more expensive to get up and running but well worth it. txt-1 is basically the same as the jugg 2, but with an aftermarket cantilever kit on it from the factory. the clod is a bit cheaper than those other 2. the emaxx wont climb nearly as well as these trucks. and electric motors have their maximum torque at 0 rpm, which means instant power. thats why it wheelies so easy.
