Fun with Counterflex and Rebound

Fun with Counterflex and Rebound

Jason Borger | Tuesday, 20 December 2016

Controlling and/or modifying blink-of-the-eye stuff is always a fun topic in fly casting discussion, especially when real physicists and so forth show up to put a damper on pet-theory enthusiasms. In any case, cheap high-speed video has made things much more interesting these days (my phone, which I believe can now be had for free with a data plan, shoots 720/240p or 1080/120p). For the geeks who dig this stuff, I've attached a few video still frames from a recent illustration project.



I'm doing this because of this thread (contolling counterflex). The thread was a couple of pages long a couple of days ago, but a glance shows that it has now grown to five pages. As a result, these images may now be moot, but I'd rather be late the party than never show up!

Anyway, these frames are from a cast leading into a Puddle Mend (a.k.a. Puddle Cast, Pile Cast, etc.). In terms of counterflex, the only active control present was my "going soft" with the cast so that I didn't provide too much "go" and mess with the desired end result. That reduces counterflex simply because the rod wasn't flexed as much to begin with. It's the next bit that I find interesting...

By moving my casting hand at a certain rate downward as the rod goes through maxmum counterflex and then into rebound, the rod tip remains nearly stationary. It's an intiguing effect, and one that I need to go shoot at a higher frame rate once it stops pouring and sleeting here. I've seen simllar results in other bits of casting, and it I think it warrants a better look in terms of rod leg shape throughout loop morph (that is, the change in shape of the loop as it propagates).

What's also intersting to me is that this effect occurs in a fishing cast, made at a fishing pace. I'm probably as guily as anyone of casting field "specials", where rod gyrations and funky loops produce all sorts of coolness and topics for the Seyloops Board. But, it's the everyday angling stuff that really catches my eye in the end, and this type of rebound adjusment falls nicely into that department. More to come (I hope)!
