The glide is okay, their grip on the uptrack is more than adequate, and they fold up easier than a stiff, all nylon skin. The skin itself is good, reasonably lightweight, too.
The glue, however, lost its stickiness prematurely on me. Where other skins easily go 2+ seasons with adequate stickiness, these lost that after one. Prepare to be adding glue of your own as a touch up.
Personal preference here, but I dislike the tip (and even self-riveted tail) attachment. I'd suggest not even using the tail rivet...
