the hcr's come with rail supports too, i highly recommend rail supports, removing the middle bogies, and putting in more crossbars, its like adding rungs to a ladder.
i dont run any bogies inless they are tied to a cross bar that way it will lift the rails up togather rather then want to twist the rail on a rock/hard landing.
iceage rails are tough, but i bent a set last year too, after rail spuports right by where the front arm mounts they have been pretty solid for me.
also make sure your shock isnt aired up too much this can cause your shock to be the bottoming out point of your suspension not your supension stops causing bent rails and bent suspension arms.
