Re: A better knot
I really like Kai's suggestion (which would work just as well as the tool I now use). Also, Rip Tide is absolutely right when he suggests varying the number of turns depending upon the tippit size.
As to the difficulties some have mentioned about tying the Improved Clinch when using very small flies, it is much easier to tie the regular Clinch knot instead. I have seen research articles concluding that the regular Clinch knot is stronger than the Improved Clinch. In my experience, the regular Clinch knot is much easier to tie than the Improved Clinch - particularly on small flies - and I have never had a fly break off when using the regular Clinch, either from the fish or from a snag.
On the whole, I'd rather be in Wyoming . . .
