Gordy -
Thanks for adding me to the list. I have enjoyed many of the email strings that Peter was nice enough to forward over the last 6 months or so. I look forward to more ahead.
A couple of thoughts on other situations where the Belgian cast works well, at least for me.
Streamer fishing tight to the bank. Like your permit cast, the goal is to cast an often heavy fly to a small target area (such as behind a log) and have a straight line to the fly for a couple of quick strips to make the fly dart from the bank. The cast is especially effective when pounding the bank with streamers from a fast moving drift boat.
Heavy nymphs in fast pocket water. The drift is short and fast and the key is again to hit a small target with the fly on a taught line to detect the strike. Good one.
One that's a little off the wall ... baracuda teasing. You probably know the technique of teasing baracuda by ripping a fly accross the water in front of its nose. A belgian cast works well because the fly hits the water on a taught line with the rod pre loaded for pulling the fly fast in front of the fish. (Note, I consider this technique a last resort after the fish has refused one or two regular retrieves but is still hanging around. It doesn't always work but I've worked some big fish into enough of a lather to strike long after they refused the initial presentation.) Yes. I often use that one. Sometimes with really big cudas on the flat, after doing this a few times, I follow up with a cast out beyond the critter and start a very s l o w retrieve. When the fish turns and starts toward the fly, I steadily accelerate the retrieve and then continue the acceleration with really fast rod tip motion as the leader knot gets close to the tip top. This fish goes for ACCELERATION better than for speed, and if you start your retrieve fast, you can't accelerate it enough.
I also find the Belgian cast works reasonably well for long casts with wind from behind. I seem to recall someone saying that the cast was invented for a tail wind.
OK... unless the wind is strong enough to blow that, "D-loop" back toward you. If that happens, you can't load the rod properly for the forward stroke.
Re the email trail below. I completely agree with your thoughts. It also seems intuitive to me. An initial translational move can take up slack, begin loading the rod or add velocity to the tip/fly line. When I go for distance, I find the key is to hold off as long as I can before rotating the rod. I focus on "pulling" or leading with the butt/elbow before rotation and it works. It may do all of these things.
You may also recall that Phillips "Technology of Fly Rods" has some analysis of the tip speeds achievable with rotation and transaltion only and in combination. His analysis makes complete sense to me. Yes. See: THE TECHNOLOGY OF FLY RODS by Don Phillips, pp. 79 -80.
Congratulations on passing your exam, Wallace !
