Hi Paul Conclusions depend on the basis one uses for comparison. Imagine one cast a 906/908/910 set of rods for a given mass of line, a given type of cast but limited by the torque used by the caster. Elastic energy storage is max for the 906, tip kinetic energy at RSP is also max for the 906, and l...

Can you show me on "The Rod and the Cast" graphs where you think that this loaded frequency begins and ends in the trace? Vince I just sent you a paper about the analysis of Matthias’ cast which I wrote in 2009. I hope you can find an answer to your question. One difficulty is that rod re...

I would think frequency and stiffness follow a similar trend, ie the stiffer the rod the more likely it is to have a higher frequency. This therefore makes it difficult to determine whether stiffness or loaded frequency is the reason an angler might prefer a certain line mass for a particular rod. ...

Hi Vince Average caster = someone able to cast 30 ft of line. Casters are a significant modification to the system and change its behaviour, taking it from fixed input/open loop to an adaptive closed system with variable inputs. On that basis, it requires a leap of faith to extrapolate the results o...

Yes Paul, it’s my « theory ». I do know that loaded frequency is important for a cast, so I asked to myself « what if » LF was a relevant criteria for rod/line fit. I then gathered information for testing the concept and in the end it was not stupid, although there will always be uncertainties. Note...

Abstracts of papers I found in my files, from Hoffmann and Hooper (the ones who worked with Al Kyte): “What most fly fishers do not realize is that there is a measurable quantity quality that can be used to describe much of what anglers feel in a fly rod. This quality which describes a fly rod’s res...

For ERN aficionados A graphic like that does not tell you a universal truth

Hi Torsten Here is a comparison between rod label and CCS result. i guess most people use ERN and forget to find the ELN which corresponds to the line. The rule is the following: if ERN is between 6.00 and 6.99, then ELN is 6. That is something people never use in fact. Below is a comparison for 111...

Hi Vince

The 20 ft story was told to me by Scott, most of the tests for small glass rods are made at relatively short distance, e.g. 20 ft.
