I'm sure I could get better with a nail knot over time. With a tube it only took a few attempts. Perhaps easier with a tool. I know they are easier sitting on the couch than they are with cold fingers on the stream.
There are variations of the nail knot as well and I may be trying to tie one of that is not as easy. I found one set of instructions on the net that said "wrap the line 30 times". Are you kidding me?
I can try most all the advice on this thread and see what I prefer over time. Thanks for the help guys.
