Paul & Group....

QUESTION FOR YOU MEMBERS OUTSIDE THE U.S. :

 

1.)  HOW DO YOU MATCH LEADER DIAMETERS TO FLY HOOK SIZE ?

Sight, experience and application - occasionally compromised with a better shot at landing the fish. I think there are other important things as well as to how the fly fishes that are not purely diameter. Such as stiffness or not.

2.)  WHAT SYSTEM OF MEASUREMENT DO YOU USE FOR LEADER DIAMETERS ?  

       a.  Fractions of inches.

       b.  Metric system (millimeters).

       c.  The, "X" system.

       d.  Other  (let us know.)

d. I use pounds b/s. (I know but the X system makes even less sense).

3.)  WHAT SYSTEM OF MEASUREMENT DO YOU USE TO QUANTIFY TENSILE STRENGTH OF TIPPET MATERIAL ?

       a. Pound breaking strength.

       b. Kg. breaking strength.

       c. Other

a but I'm happy with b.

4.)  WHAT CAN YOU TELL US ABOUT YOUR CONVERSION FORMULAE ( IF ANY).

I don't have one.

Cheers, Paul

System, new to me, from Bill Hagashi (Japan) sent to Dan McCrimmon and then bounced to me :-

Here is an explanation of the Goh-system from Bill Higashi (MCCI - THCI). This system, like the X system does not indicate breaking strength.

 

Hello Dan,

It is a system based on the diameter of the material.  Here is the standard used by one manufacturer.

0.6      0.128 mm
0.8     0.148 mm
1     0.165 mm
1.2     0.185 mm
1.5     0.205 mm
1.75     0.218 mm
2     0.235 mm
2.5     0.260 mm
3     0.285 mm
4     0.330 mm
5     0.370 mm
etc. (Standard used by Yotsuami Co, Ltd)

0.8 goh is about 5x, and 0.6 is about 6x.  However, this standard slightly differs depending on manufacturers and they also use Goh system for gel-spun or Dyneema, which makes some confusion because they are not round material, far stronger than nylon and impossible to measure the diameter.  Goh system doesn’t indicate breaking strengths.
