Mike,

I would go for the cleat that Mooch posted over the alum one. I have the Alum one on my sled for my river anchor. I HATE it! Several times I have had trouble getting the rope free from the cleat as the weight of the boat has pulled the line into the cleat so far that I can't pull it back out. The cleat that Mooch posted wouldn't do that as the pulling motion will automatically loosen up its grip. So if you haven't already installed the plastic one go get one like his! You'll be happy you did.
