At first I was real impressed with the superlights, they fit into smaller placements and they were lighter. Upon further review and use, my views changed. I realized that I didn't shave that much weight of my trad rack by going with the superlights (about 3 oz.). I also noticed that the strength rating on these babies are the same for a normal rock placed on its wide axis which is its weakest position roughly half the strength if placed on its narrow axis. When using them I found myself wishing I had all the options of normal rocks (wide axis placement/narrow axis placement). I guess I would recommend these as a light-weight second set of rocks on your rack.
