Hey bud, you'r last post has the idea however, I had problems (especially on hair bodies)
with the roundness of the monoline.
I was melting some mono for small weighted eyes, it leaves a small loop with two round
drops of the line the looks good on my small panfish flies.
Any way, as far as a week gard, it came together when I heated the ends of an old set
of forceps and clamped the ends of the line by about a quarter ench. This way the tied
on ends of the line that form the guard tie flat to the shank, and I think the wrinkled
ends of the line under the body help make the guard last longer than body of the fly on
a hard bitting day.
good luck at the vice.
