Nathan, what you're saying is anecdotal at best...regarding the aluminum "grabbing" onto rocks. That would either speak to the coefficient of friction for aluminum vs. steel if it's a matter of sliding. Or if you assert that the rock is bearing into the material, forming a groove and catching that way it also speaks to the (Rockwell) hardness. I've honestly never compared the average hardness number of the two materials, but I have a tough time believing that the difference is palpable enough to give steel the nod as the better material (in CA or WA) considering its density vs. aluminum and the fact that aluminum doesn't rust (as easily?)
BTW, we have rocks up here too!
