Aitor Coteron once again brings us a very insightful and thought provoking casting lesson all through the simplicity and non-arguable use of slo-mo video analysis.
as noted in the video, if the fly and rod legs aren’t parallel prior to the forward cast there’s a great deal of ‘misplaced energy’ needed to straighten the D-Loop out before the line can actually start moving forward. in a way, this is the equivalent of having slack in the system even if this slack isn’t apparent and it all seems nice and tight.
the beauty of slo-mo analysis shows this clearly when the apex of the D is moving perpendicular to the casting plane instead of inline with it.
sure, even with a sloppy anchor placement the casts still works (up to a certain point and this will be greatly influenced by the length of the line’s head) but who wants to be sloppy ? it’s much less efficient and regardless of head length we’ll notice that since the leader and fly are off to one side, once delivered, they’ll swing to the other at the completion of the cast just like when we swing the rod tip throughout the stroke in an aerial cast. in extreme cases, this will lead to line collision, a somewhat equivalent of a tailing loop. not good.
what this all tells us or rather reminds us of is how important it is to learn and work out how to be as efficient as possible by regularly practicing getting anchor placement not only in the right location but in the right angle relative to the direction of the forward cast.
to finish off i’ll add what may seem as a minor rant but it’s intended to deepen our understanding and progression through analysis of this subject. go on Vimeo or Youtube and check out the casting hotshots and also your fishing/casting mate’s anchor placements and angles when on the water when out with them. i can’t put percentage numbers to this but you’ll notice that the vast majority have less-than-desirable anchor/D placement. work on doing it better than them 😉
