Re: Salt Water fly cast
I believe Lefty's method is easier for most casters, as it will help prevent your fly from hitting the rod tip. Just make sure your right-foot, assuming you're casting right-handed, is behind your left foot.
Also, if you use a drift move, using Lefty's - rather than lowering the rod to, let's say, 2 o'clock - will help prevent you from adding slack in the line.
To me, one of the big problems with Lefty's method is changing casting trajectories, but that rarely has to be done when casting in saltwater.
Also, when I tried casting Lefty's way I couldn't get my body to fully rotate.
