I have the honda setup (KFI) I went with the 72" composite plow because it's light, and if you don't abuse it, may virtually last forever. Also the KFI Stealth 4500 lb winch with the rope.
I plowed once this year so far with it 9" of snow, no problem. I leave the feet on the plow with just 1 small shim so the cutting edge doesn't touch the ground. Feet are much easier and cheaper to replace than a cutting edge is. The residual skim coating of snow will melt, or is at least easy to drive on.
Sorry for crappy cell phone pics at night, all I have for now.
The only gripe I have is that I wish I had the ability to angle the plow left and right from inside the cab. You can angle this manually. There is a plow out there with hydraulic pistons, but it costs thousands of dollars and isn't worth the price difference in my opinion unless you are using this machine to make money with.
