So i've had a pair of Dutchware Stingerz for a while now and i love em. I use them on every tarp i have that has soft nylon pullouts, but i'm hesitant about using them on tarps with hard plastic d-rings like a clark or hammockgear. I feel like the metal on plastic just isn't good idea, especially in cold weather. I just have a feeling that they are going to dig in too much and wear them out prematurely or worse, crack them.

Am i the only person who worries about this? Am i over thinking it?
