Yeah, I think a sawed off standard mast with a radial sail might be harder to sail in a breeze than a proper standard rig. The proper standard rig will bend a little, but the franken-Radial won't bend at all.
ON fresh water?? Unless it is bent it is ever so slightly better than new and improving with each use.
In fact, the only way to win races with it is to go sail it some more.
