Change a bulb for me.
If you don't shoot line, you have little guide friction, but you do have the resistance of the flyline transfixed at the rod.
Also, if some practical joker cuts your running line (which happened here, a while back) and you shoot line, the cast goes out to kingdom-come. Reason is that this effectively removes all rod resistance and the loop takes much longer to unroll and does so only because of the inertia of the more slowly travelling cut-off rod leg. Theoretically, it would go even farther were it not for air resistance and the effect of gravity.

Howdy Gordy,
I got thinking on this as I was changing lightbulbs
The Fly leg speed would be the loop speed minus the rod leg speed times the loop ratial speed due to the Diameter of the loop. with the decreaseing speed of the rod leg due to the drag on the guides. NOTE: This drag is needed to maintain a loop much like flying a kite if you let go or the string breaks the kits flying abilty is lost. It just futtlers to the ground.
The loop with out the rod leg drag is no longer a dynamic loop.
More to think on.

AHAAAAA !!! You are correct about that.
The physics papers I've studied have all dealt with a simple cast with no line shoot. As soon as line is shot, a whole host of calculations change.......and as far as I know, none of the physicists have tackled those in print.
There, we get into stuff such as the amount of overhang being the barometer for the RATE OF TURNOVER of the head as being inversely proportional to the ultimate distance for the cast.....and much more ! (Jason Borger quoting Steve Rajeff in, ""THE NATURE OF FLY CASTING"", pp 240 - 241.)

Howdy Gordy,
All of this was neat to know BUT I shoot line in to my Cast.
Now the rod leg is moving at a rate of unknown speed in the direction of the cast.
The loop is not not just flying out at a X speed it is sliding along So the Fly leg is moving at a rate less that the Circluar amount of the Loop.
This is what provides the later turn over of the loop/fly. So now we have to go back and refigure the loop speed, rod leg and enter that in to something that would crack an atom.
I got to work to night to find Jim had aswered all the easy questions. That I had a chance at.
Thanks
