Walter & Group...
[GH] From Jim Gill,
Hi Gordy, Just to let you know that despite my lack of activity in the debate, I have found these "discussions" extremely helpful - especially as I'm preparing for my GAIA advanced assessment. This one in particular (Walters' notes) have clarified an area of confusion that I was faced with whilst practicing yesterday. Today I'll go back out and experiment further - once I've understood what is happening I'll feel I'm in better control.
Best wishes, Jim.

[GH] Going back to Task 11, discussion 5. I'd like to quote one excellent passage from Walter Simbirski and follow with a brief comment :
"Another advantage to using a horizontal casting plane to dial in distance is that there is little reason to hover the fly when you do this. One of the reasons for hovering the fly with a closed stance and vertical casting plan that your view of the fly is time limited. You make your forward false cast, wait for the fly to enter your field of view, acquire the target, make a lot of complex judgements in your head about a fast moving target in a few tenth of a second, and then the fly is gone again. Our field if view is actually narrower vertically than it is horizontally .
A vertical casting plane actually gives us less time to do these things. In addition, with the vertical casting plane we need the fly to be in the region where we have 3D vision in order to make depth of field judgements. In the horizontal casting plane (with open stance) we are able to use our wider field of view to watch the fly for a larger percentage of the time. In addition, since we are less reliant on the section of our field of view that is 3D, we can keep both the fly and the target in view throughout most (or even all) of the cast and get useful information the whole time so you find there is usually no need to hover the fly."
I agree with Walter's assessment. He combines the disciplines of both physics and optics very well.
One small addition : I do see another advantage in hovering the fly. That is delicacy of presentation. This is especially true when I make the effort to hover a weighted bonefish fly by using an upward vertical curve cast. What Joan Wulff called an "upward curving power snap". An accuracy vertical curve cast presentation.
Delicacy of presentation is also an obvious advantage when dealing with wary trout in glassy calm conditions. When dry fly fishing, most trout fishers do it with vertical plane casting..... however, with practice it can be done very well when casting in the off-vertical or even the off-horizontal plane.
