Everyone has a favored forward foot. I always thought "chocolate foot" was the same as "goofy foot" - just the less common foot forward. But who the %*#* am I to argue with Hans?!
So try this: make a habit of forcing the reverse - when the descent is easy, ride with your dominant foot back. The more you do this, the less awkward it feels... so when you're caught in that position, e.g. mid-stroke, and have to maneuver (bunny hop, hard brake, swerve, whatever), you're more comfortable.
