That is exactly what I do. It's just a little helper haul that I developed--unconsciously--to help deal with wind that seems to be ever-present out West.Okay so, perhaps I'm just generally screwed up, and I have performed classic "double-hauls," yet I do something slightly different in my regular casting that I wonder if there is a term for beyond the "what in the hell is wrong with you" cast? Up front know this however, I jumped from light line fishing to heavy heaving (like 14wt.), and really enjoyed distance casting so much that even today I find it very difficult to simply cast in a relaxed fashion, arms low and single handed. So maybe I am just messed up.
Anyway, what I do is (and imagine a double-haul), on my back-cast I'll draw the line forward (though not to an extreme at first) approximately half-way I can reach. I then begin my forward-cast passing my line hand, then pulling my line hand back. So instead of making the extreme down/up motions with my line hand to full extension, it only plays out half-way at first. As I get more line out making a couple false casts until the final forward cast and shoot, I will gradually increase that line-hand motion, yet I rarely do it to the extremes these guys were showing.
