I had one inexplicable breakoff with Yozuri Hybrid 10# as leader
about 10 years ago. Scared me off it for a while, but I've been
back for a number of years.
That said. I bought some clearance hooks at Walmart - Daiichi.
I lost several hooks when fishing. One day, as I was tying on a
snell to a worm hook I broke the line as I tightened/tested it.
Did it twice and on the third time I paid closer attention. Broke
again. But this time I ran my fingers along the hook eye and
found it was rough and a snell was rubbing on it. I lost all
confidence in the hooks, went back to Gamakatsu and no probs
since.
That said, I believe a NON-snell knot would have been fine.
And as intimated above, the entire package: line, rod/rod rating,
reel, drag, all contribute to the experience. If drag is too tight when
using lighter line, boom. Disaster.
