Hi, Group....
Some minutiae questions on fly lines:-
1.) How great an advantage is gained by having a very stretchy line for distance casting ?
2.) What is a density compensated fly line ?
3.) Does the TT line (Triangle taper) have a convex compound forward taper, a compound concave taper, or a strictly progressive forward taper ?
4.) If I buy and weigh several Cortland and Scientific Anglers WF fly lines, will I find that they all have approximately the same weight range for the first 30 feet if the stated designation on the package is WF7F ?
5.) Can you name 3 different fly lines which have no belly ?
6.) I am casting with 50' of an XXD, WF6F fly line out of my rod tip. What weight fly line am I actually handling ?
7.) My student shows up with a 5 wt rod. He's placed a WF7F line on it. How much line should he have out of the rod for easy false casting ?
9.) In 1962, the AFTMA came up with the present method of designating fly lines by the grain weight of the first 30 feet. What is the PRIMARY difference between this method of measuring fly lines and the former method which was stated in letters ?
10) Can you tell me one disadvantage of a fly line which has a gel spun core of Spectra ?
11) I just bought a full sink WF 10 S, TYPE VI fly line.
