Actually, I was just working on the basics with a Switch Cast, so river orientation is not critical. The switch cast is just an exercise to develop the basic lift, loop creation and fire, that all change of directions casts, like the single spey, are based upon. I do try to find places to practice both river right and left casts, when working on my single speys and snake rolls. I also take the opportunity, regardless of river direction to always spend sometime "Switch Casting" left and right handed to build muscle memory. Thanks Klick, keep it coming. James.
