And Another Thing

Why does the loop have the ability to pull the rod leg and allow us to shoot line? As I understand it the line decelerates as it goes around the loop but as it gets to the bottom of the loop it comes to a sudden stop as it runs into the rod leg which is a bit like you hitting the brakes in your car and you surge forward only when it comes to the loop this braking effect becomes a continuous chain effect until either the line turns over or momentum is lost in the fly leg which destabilizes the loop and the cast collapses. The breaking effect would be greater in a narrow loop than in a wide loop because the deceleration around the loop face is faster because it has less distance to do it in so the braking effect and therefore the pulling power will be stronger. When shooting line  the braking effect must be reduced somewhat although it will still be fast relative to the speed of the fly leg.

There is obviously tension in the loop face or else or would collapse and it seems to me that tension will be greatest where the breaking effect is strongest, the bottom of the loop. And, there is sufficient tension all around the loop that if we pullback for any reason that pullback is transferred all around the loop, pulls on the fly leg and adds directly to line speed  in exactly the same way that hauling adds directly to line speed. The loop has to speed up as a consequence because, apart from drag forms, it is the servant of line speed rather than the other way round.
