From Bruce Richards :-
Thanks Gordy, very interesting answers, and few I could really argue
with... I like to think of the haul in terms of what we are trying to
accomplish. I see two main goals, adding line speed, and maintaining as
straight a tip path as possible. SLP comes from a progressive rod bend
generated by constant angular acceleration of the rod. As you know, we've
done a bit of scientific study of hauling and have gotten some interesting
results, although too few casts made to make any generalizations.....
If the haul starts at the same time rod rotation starts it is easy to match
accelerations to maintain SLP and gain tip speed. There is no disruption of
the bend caused by a tug on the line in the middle of the stroke. This
works and is the way many casters haul, and is the way I haul, at least on
my forward cast.
The haul can be delayed past the start of rotation though, without
disrupting rod bend. It appears that if the haul is very late, once the rod
is deeply bent, it will not necessarily disrupt the bend as the rod tip is
largely in line with line and is much less likely to dip below SLP even
with an abrupt haul. The haul may pull the tip back a bit, but won't move
it down much as it would earlier in the cast when rod bend was less.
I've attached a paper that Noel and I did after studying hauled casts I
made. These were not max distance casts, our rather fragile haul analyzer
wouldn't allow that. I've made some notes pointing out some key things on
the Excel chart also attached, let me know if I can explain anything
further.
