Can we sift ANY information and insight from this complex soup? I think so, by considering three different models for at least some of what is happening. And note that more effect of one model may reduce or replace the effect of the other two models.
Consider first the haul in it’s most simplistic terms. One is PULLING DOWN on the line with the line hand. All previous discussion of the Loading and Acceleration Phase assumes that line movement is zero, whether the line is held under a finger of the rod hand (as I did for my rod loading photographs), or held static (to the rod) by the line hand only to the effect of preventing movement out the back of the tip top.
Imagine for a moment that line friction is infinite, the equivalent of a knot on the first stripping guide so that ALL of my pull is directly pulling on the rod at the position of that stripping guide. That first stripping guide is a long way up the rod and there is a lot of leverage up there. In that WORST CASE scenario, what are the forces on the rod?
