I am relatively new to sliding rails etc.  When I first started, I didn't know which side was "natural" so I picked right leg fwd and went with it.  Having recently been on a skateboard for the first time, however, I find it a LOT easier to ride left foot fwd.  Does this suggest my "natural" rail slide is left foot fwd?  Have I learned the hard way?  I have never tried to slide left foot fwd on a rail
