Counterflex & Follow thru - interaction?

Post by Bernd »

Hi everyone,
Paul said (if I remember correct) he doesn't know how to reduce cf unless he avoids/reduces rod bend during acceleration.
That made me think cause I in some of his casts thought to see less cf compared to other casts while having almost the same max rod bend.
Here are some of my thoughts about how we (maybe) can reduce cf by a fast follow thru.

You may want to check where Paul positioned his rod butt during the stop.
Watching the whole video it seems to me Paul lifts and moves his rod hand forward while in addition tilting rod butt angle down. That seems at least to dampen rebound almost totally. But I think it may also reduce cf?

Bernd,
Thanks for taking the time to generate some data relating to the "thrust/follow through" issue.

Are your violet vectors actual velocity vectors computed using Tracker or did you do it some other way?

I would expect the magnitude of the velocity to have much more change that these are showing.

It appears that he is damping the counterflex by that movement but he could also do that be relaxing his grip. In either case, it is likely that he is trading tip velocity to minimise the counterflex.

Hi Gordy,
the violet vector is just a photoshopped arrow showing the degree of drop of Paul's rod. As well as the white point marks his hand position like it was in the first pic. Just to get a good idea of where and how he moves his rod hand and at the same time changes the degree of drop.
Due to his movement he follows the cf. That (I think) reduces it. Sometimes Paul don't puts the rod butt aside his forearm. Am pretty sure that results in more cf. Since he does not drop the rod and following cf that much in case.

Bernd,
You might try digitizing his hand path with Tracker and getting the actual velocity vectors. Alejandro has used it to good effect and it will work with any type of video file.

You can download it at:http://www.cabrillo.edu/~dbrown/tracker/

Just since his arm is extended in all those framegrabs I do not think there will be much hand velocity (or acceleration) in that cast after RSP1.

Any particular reason for this choice in colour Bernd? :???:
It's an exploration; bring flyrods.

No :D It's just a colour.
Thanks Gordy,
I check and try to work it out!

Interesting to see Paul's hand path Bernd, and the white vectors against the background.

3 posts is way too soon for a proper shoeing.. it would be too rude...anyway when it comes it won't be because you're a poor caster....its usually about over asserting a general and persistent wrongness...my first shoeing was failing to agree that a nail knot was a capsised uniknot, or visa-versa, can't remember now...brutal...I had to have psychotherapy for fkn months... :)

Not til 2.30, been to the gym, got some buttonholes, ironed my shirt and said F**k off a few more times to people who want me to wear a tie...some of whom are already drinking... then I'm going to watch the football with the therapixies.

Nice day for it...bring a fan... :)
