[GH] Jim Chestnut takes up Bill Keister's challenge and "pokes a hole" :
Hi Gordy /Bill,
" However, hauls cause the fly rod to bend so hauls must occur prior to
RSP."
What hauls cause has no bearing on when they must occur. They must occur
whenever the caster executes them.
In this video of Steve Rajeff casting one of the frames around 1:07 shows
the rod already in counterflex, yet Steve's hauling hand has not yet
appeared behind his side. This can be clearly seen by hitting the stop
button at exactly the right time on his presentation cast.
So the effect of a portion of the haul in this case (in addition to
increasing line speed) would have been to slow counterflex or reduce the
bending of the rod.
Cheers,
Jim

[GH] Look again at Steve's cast. Note that despite his elbow-forward-vertical-rod plane style, he looks back at his back casts. Steve has explained that when tournament distance casting, he tries to pick his best back cast loop prior to making his delivery cast. This also explains why he doesn't always use the same number of back casts.
Oft taught: "The back cast is the set-up for the forward cast."
Also, take note of Steve's final haul on his delivery cast. It is faster and longer than the prior hauls.
Reminds me of something Lefty Kreh taught me years ago on a Bahamas trip. When I was applying too much effort on my final delivery cast and ruining what had been good tight loops on my false casts, he stopped me and said, "Try using no more power on your final cast than you did on your last false cast; just haul faster. Let your haul be your accelerator." Worked great ! I never forgot that simple advice and often use it as I teach.
Of course, in tournament distance casting, one doesn't want to give up an ounce of energy so Steve and other champion casters often do both..... max energy on the delivery cast combined with a long / max. rapid haul. They can get away with this because they have become expert in maintaining an almost straight line path of the rod tip with good loop control despite the combination of carrying a great amount of line while using maximum energy input resulting in a good match between the casting arc and the rod bend. (I can hardly bend Steve's rod ! )
When Steve makes a long cast from my skiff to a tarpon, he never does that. Why ? Because he's got an eagle eye on the fish and its travel pattern. Results in his deadly accurate fly placement.

[GH] John Symonds replies to Bill's challenge :
Hi Gordy,
I agree with Bill Keister but this only applies if you consider the fly-rod movement in isolation. Like I said in my previous email rotation of the fly-rod at the butt has a much greater influence on rod-tip velocity because of the fulcrum position which greatly amplifies rod-tip movement and velocity relative to hand movement. Consequently, this has a greater influence on the rod-tip velocity relative to the ground and so it usually causes maximum rod-tip velocity in advance of RSP.
Best regards - John

[GH] The concept of the fly rod being, among other things, a long flexible lever. The longer the rod, the greater the magnification of hand movement to rod tip travel. As we reach diminishing returns due to difficulty in handling very long rods, we morph into two handed casters.
