I'm probably in the same boat you are bro I'm a average garage mechanic and can figure my way threw most stuff to get the stuff fixed so sometimes I need the part to fail so I know what needs replacing. For rails I'm really not sure what I'm getting right now I'm kinda of lost. Balancing cost and function is pretty hard. Doc's and 4xGuards rails although tough as nails for sure they are both very expensive. In a perfect world getting the 4xGuard rails with doc's tub welded to the out side seems like the perfect setup which in the end will probably be a $800 setup
