|I tied a few traces with .70 fluoro, snelling the circle hook. A standard snell kept on unravelling when tension was released. I searched to find my problem and found the improved snell knot, where the main line of the trace passes back under the 1st loop. I thhen tied a few circles, much better, but I could still (with a bit of effort) unravel the knot. I decided that they were fine.
I was tying again last night, and decided to experiment. My best solution was the following:
1) Thread the tag end through the eye as per normal.
2) Thread the 1st loop, but not over the tag end, under It, going around the hook only.
3) Lay the tag end as per usual against the back of the hook.
4) Thread 8 (this will differ depending what line) you're using)
5) Thread mainline under the 1st loop similarly to the improved snell.
6) Pull tite by pulling on both tag end and mainline.
Basically it's one step extra by creating the 1st loop under the tag end, and the rest over it. I don't see how it would hurt the breaking point of the line, but I have not done any tests. It is much easier to thread the mainline through the loop on the way back, after the eight loops.
The knot pulls very tite and it it very neat. Try it - tell me what you think.
