I have the normal steel one. I went into the store to get the poly one and after comparing the 2 I went all steel. The poly was pretty rough to be honest. Looked cheap and not well finished. They look really good in the pictures I have seen so maybe this was just a bad apple.
Another thing though after looking it over I figured it would look really bad after the cylinder (steel) got some wear on it. A worn steel cylinder against a poly frame does not appeal to me.
But if the finish one the one I saw had not been so rough I might have gone with it. After all they do look really good in the pics
