I've been flyfishing for a while now, and recently encountered a "new" problem.

I tie my leader to my flyline using a nail knot. On my last couple of outings, I've run into problems with my tippet catching on the tag end of the nail knot. I've trimmed it down to about 1/16th of an inch (as far as I can clip) and it still snags. I'm guessing I've made some unknown change to my casting stroke, because this is a new problem for me.

Anyone else have this problem? I supposed I could change knots, but that won't necessarily help with whatever has creeped into my cast.

Anyone offer a solution?
