I have the rubber ladder rail covers with the scalloped top covering the whole top rail and just got XTMs to use on the sides
I really like the ladder rail covers as they are light and the scalloped middle allows for a nice grip if you use them on the sides as well
the XTMs fit real nice and secure but they seem to add quite a bit of weight and increase the size of the griping area quite a bit as well
I am thinking of using the ladder rail covers for the whole thing to keep things slim and light weight. I am sure the XTMs provide better protection against nicks to the rails but they do seem more bulky compared to the ladders.
so I am going to try both ways or a combination of both to try to find the best fit/weight ratio that works for me.
