[GH] From Mike Heritage :
"GH] Another fault which can result in either a collision between the fly line and the rod or a tailing loop is found in the fly casting literature. Jason Borger divides the cast into 3 phases. Phase 1 = Acceleration. Phase 2 = Loop formation. Phase 3 is Energy Transfer (the stop sequence). Throughout his text, this is revisited as ALE."
Sorry Gordy, I find this comment totally confusing. Shouldn't phases 2 and 3 be the other way round, Energy Transfer (the stop sequence) leads to loop formation.

[GH] Mike,
Let me quote Jason Borger directly on what he called "Phase three". On p. 26 of the same text, he wrote:
"Phase Three (Energy Transfer (E) has a less descriptive but more common name; the stop. at the point in the cast immediately following Loop Formation, arm and hand motions are stopped (Fig 2-12) .This allows the rod to unload, transferring the rod's stored energy to the line. In addition, the unloading that occurs when you enact Phase 'three essentially continues, and then finishes, Phase Two. Indeed, Phase Three is what allows the phase Two motion to be an effective element of loop formation."
With regard to your concern over the order of his phases, he then writes, "All of the three phases must be present and must occur in order (One-two-Three or A-L-E) to have a cast. For example, you cannot stop (Phase Three), then form a loop (Phase Two), then accelerate (Phase One) or form a loop (Phase Two), accelerate (Phase One) and then stop (Phase Three). The order of One-Two-Three (A-L-E) must be there. "
I must admit, I didn't find it easy to get my head around this, either, for the same reason you found it confusing. I began to see what Jason was getting at when I read the entire chapter including his diagrams. I can also see why some might disagree.

[GH] From Gary Eaton:
Gordy,
You stated, " . . .taken issue with Lefty's statement on loop size being determined by the distance that one speeds up and stops."
I am one of those who take issue with this statement. The loop width is determined by deviation from straight-line path during the delayed rotation phase approaching the stop plus counter flex. All in-line casts accelerate ("Speed up") from beginning to the end of the cast ("Stop") when the loop is initiated. Lefty's statement states that the "speed-up" occurs only at the end of the cast. Lefty's wording is dead-wrong. The more correct phrase to be substituted is "rotation" or "convex tip path". Acceleration should, ideally happen at a continuous rate from initiation of tip movement - smo-o-o-othly.
Rotation increases tip velocity at a greater rate than non-rotational rod movement - acceleration. Absent significant vertical adjustment of the casting hand, this rotation causes vertical change in tip path, typically under the path of the line. As the stop is generated with abruptness, further tip deviation in this direction, usually occurs with counter-flex of the rod. These two elements provide the mechanical sources of loop width - not ". . .the distance that one speeds up and stops."
The incorrect statement must be noted as incorrect when it is so. This rejection of false premise transcends the conveniently understood mis-application of definition technicality such as those between "force" and "power".
I have more to address on this post, but must go to work.
