Because I was not seeing that many fish but also because I was seeing a high incidence of fish over 15 pounds I just randomly decided to see if I could keep myself from casting to anything less than a fish that appeared to be 15 pounds or better. There have been days, just a few really, when I have caught so many large fish that I just can't be bothered fishing for the 8-9 pounders. Please know that is nowhere near normal. This day it wasn't that I was catching so many fish; it was just that I wanted to see if I could keep myself from casting to 8-9 pound fish even if I wasn't seeing large fish. I wondered how long I would go without getting at least a shot at a large fish before I decided that this wasn't really a fun game after all. I wanted to test my discipline.
Temptation called me several times, I was "strong", I resisted the 8 pound fish. It wasn't totally easy because 8-9 pounders were most of what I was seeing. Enough large fish were taking my fly that I "held up".
