Having used the ski’s, and the UHWM, the ski’s are easier to install, a little thinner, but not very wide underneath. I finally did all mine in thin 8” wide stainless steel strips, counter sunk the stainless screws, and sealed with silicone. The UHWM can really put a lot of stress when running in since it is thick, and beveling is not enough. And when others mention glue; there isn’t a glue that adheres to the darco 100%. I highly recommend the stainless steel approach.
