JC I always have a tough time reading you... I can't always tell when you're messing with our heads-- seems like you should be the advocate of a knot with your name on it.

Unless you're not messing with our heads. Personally I had no problem with the Castwell for a year, but then lost 3 leaders in month. I found the knot was fine under tension, but if you pushed against it in compression it had a tendency to unseat and slip. I don't know why one would do that to a knot, other than to test it, which is probably why I lost those leader. But I suppose it could happen.

I chalked it up to user error, its quite possible I wasn't tying it correctly. Non the less, I bought a nail knot tool, and have knot been happier. Performance-wise its the best knot I've tried... just takes a little longer.

And yes, it is a problem to lose a leader beyond the $3. Loose line in the water is an animal killer.
