From Troy Miller:-
I believe I disagree with Bruce significantly on the major benefit of translation, as I mentioned before Gordy. I plan to prove this by taking a flyline and laying it on some sort of surface to support it. Then I will slightly pre-tension it, to assure that there’s absolutely NO slack in it. Then I’ll see if I can cast it as far using rotation only, as I can with my translation/rotation stroke. I already know the answer, but I intend to logically prove the point. Then someone will tell me that I’m making an invalid test, since there will be friction of the flyline along the support surface, so I’ll have to Teflon coat it, yadda yadda…
The point is, that I believe that having substantial velocity before getting into major rotation is more important than slack removal. Velocity is directly proportional to momentum, and having some of it before rotating (I think) allows more efficient continuation of rod loading (thus more accurate and consistent SLP). If we don’t have any velocity before starting rotation, neither do we have momentum (in rod or line). Further we don’t have rod loading. I don’t know if there will be a valid scientific method that could prove this one way or the other…

Troy: I knew that. You had so indicated to us in the past. I also had reservations about taking up the slack being the only important aspect of the translational phase. That's why I worded my message the way I did. My own take is that both the velocity and the taking up of slack (if present) are significant. In the theoretical case of a cast with absolutely no slack, the value of velocity before rotation would likely be the major value. It may be so in the event of slack since the velocity and momentum help take up this slack.
I'd also like to point out that we are talking about a specific cast.... the straight line overhead cast of sufficient distance to make the graph measurements significant. At this point, I frankly don't know how all this would apply to Spey casts, other elliptical casts, and the roll cast except for its forward stroke.
Additional studies will be needed to determine all that.
We must remember that the Casting Analyzer only measured angular acceleration, not translational movement.

Hey
Gordy,
I concur with Guy’s
response to the use of the Belgian Cast. I noticed that when using a
tandem setup such as a dry fly and nymph combination and fishing it about 8” to
10” apart, the cast was subject to tangles with a cast without continuous
tension. When teaching the Belgian Cast with its continuous tension on the
“line” with a change in rod plane and the point of using this type of cast to
deliver a dropper rig to a target, helps some students really understand its
use.
Thanks,
Ron

Agree. Good teaching tool to make the point, Ron.
