The solid axle is predictable you will find that this is very usefull once you get to know the rig. Independent rigs are mostly used as rock racers. Also alot of flix is cool but is very unpredictable and often puts a wheel in spots where it doesn't need to be. Cracks,holes or it also creates alot of body roll. Theres alot of difference in a rock racer and a MOA crawler.
