those look good, I haven't looked that hard but the ones I saw were all metal and with me already dragging ass I was afraid of the added weightYou don't have to buy a full set of skid plates, but I would highly recommend it. The protection they provide as well as the peace of mind when you drag your belly over a rock or stump is worth every penny. Lot's of folks swear you need 1/2" skids. I live on the rocks and 3/8" is plenty good enough for my machines.
