Since I play a Redan all the time on my home course, I have come to believe that it is better to play a cut INTO the slope rather than a draw that runs with the slope. Far easier to control the roll of the ball that way.
And any (righty) who regularly plays a draw fears left, and the Redan bunker runs away from you, right to left, so any slightly pulled or over cooked draw just goes deeper into the trap. "A slice will listen but there is no talking to a hook..."
Of course, today's aerial game permits this approach to a Redan, and that is a little sad...
