We usually say about masters in any discipline that “they make it look easy”. Probably it isn’t just that it looks easy, I have the conviction that they look so relaxed because… well, they are totally relaxed.
As my fly casting mentor likes to say, a long cast starts in the tip of the toes and ends in the finger tips. Less extreme casts have less body parts in play, but share some important trait in common: good form requires to be as effortless as possible.
In everyday trout fishing casts, our main engine is a combination of arm, forearm and hand. That is why fly casting manuals recommend to apply force with the hand only at the end of the stroke: just around the stop.
Closing your rod hand tight only at the right moment, and for a brief time, makes a lot of sense. Open and close your rod hand while holding your forearm with your other hand, and feel how many muscles get tensioned by that simple exercise. This offers an explanation for that ache starting in the neck and going down the back, so many of us feel after a long day on the river.
I have no idea about biomechanics, but my gut feeling tells me that muscle tension and accuracy are rather incompatible. Just another good reason to train the closing-opening of the hand during the casting stroke.
But truly relaxing the hand is pretty much impossible if we departure from an inadequate starting point. Every time I see someone casting with his reel parallel to the casting plane, I know that things aren’t as effortless as they could be. They say that a picture is worth a thousand words, so if it is a video probably even more.
I must confess that just making a few casts with the rim of the reel facing the target felt totally uncomfortable, as you have to constantly force the rod to keep the reel in place. The same goes for an overhead cast, as we normally make them with a slight inclination to the side.
One day this Autumn I handed my rod to the guide and asked him to show me his long nymphing approach in a particularly deep run. I immediately noticed how he got the reel in the “hanging”, relaxed, position. I asked him why; “balance” he said. A much more concise way of conveying the same idea.
