[GH] From Paul Arden :
Thought I'd answer this one too Gordy!
Cheers, Paul
1.) Are any two casts identical?
Like snowflakes? Maybe.
2.) Does it matter where a loop is first observed?
We have enough trouble trying to work out when it actually forms in theory, let alone practise, so no.
3.) How would you recognise loop formation?
A loop is a length of line curved around itself.
4.) and if it could be observed how would it help you to teach me?
A beginner has to understand the concept that in flycasting we're forming a loop. Apart from that you could probably get into some interesting arguments over definitions.
5.) Defining “useful energy” as that which is the line requires to extend correctly. When does the rod cease to provide “useful energy” to the line?
MCF... possibly RSP2.
6.) Is it possible for the line and rod tip to travel together without useful energy interchange?
Yes.
7.) If the mass of a fly line is considered to concentrated at a single point and the rest of the line is considered weightless does this help to illustrate the location of the line launch direction?
No.
7.) If the line is now considered to be a chain of different link sizes to replicate the taper what change does that make to your consideration?
It doesn't make any change to my previous answer. However considering the line to be a series of connected links is useful.
8.) Does the line launch direction indicate where useful energisation of the line ceased?
No. That would ignore line tension in the rod leg necessary for loop propagation.
9.) It is better but is it absolutely necessary to have a rod that bends?
No.
10.)
f. Because of the considerable amount of overhang involved.
