Sitting on the stone it's an easy mantle. From below its extremely contrived. This problem is better avoided I think.

if you sit on top of the stone, its maybe a 6A even less. If you get in the hole and lean against it you have kind of a right heel hook but what? Its still a lot easier than 6C+ and like the other comment said its contrived. Try it, downgrade it, be happy 1 star
