Hi everyone.James9118 wrote: What I think happens in pull back is that it sets the loop up with more angular momentum. Rather than the line overtaking the tip as a result of the imparted velocity and forming a loop in a normal way, with pull back the loop formation is more 'aggressive for want of a better word, and as such has more angular momentum (although the linear momentum may be exactly the same).
First of all what is pull-back?
Pull-back to me is about pulling the fly line (rod-leg) almost opposite directed to the casting direction. In my understanding it (the particular tip movement) happens mainly post the start of loop formation.
James could you explain "angular momentum" here further for me, pls.?
What I am sure about:
- Pull-back significantly speeds up the unrolling of my bc.
- Depending on how strong of a pull-back I add the unrolled line has huge (clearly increased) tension.
- The unrolled line can (if I add large pb) pull very strong on my rod tip! Always feels amazing to me.
- It helps to tighten the loop.
The "trick" for me is to add huge pull-back but be ready with it before the rod-leg has too much mass. That way the much heavier (I think increased) momentum of the fly-leg can easily overtake the relatively small momentum (little mass) of the (still) short rod-leg.
If I am too late in finishing the pb it no longer works. I remember it took me a long time to get that technique really working. I have shown it to many instructors and most could not just adapt that technique either.So it seems very critical in adjusting the perfect timing.
My question is: Does pull-back speed up the (whole) fly-leg relative to the ground/target? I think yes.
But I yet haven't got an explanation matching physics here.
