Well, I have used the improved clinch knot for awhile and NEVER had a fish on that broke the line at the knot..and that is with lighter line on mostly salmon-steelhead in the 7-35# range using 12-25# line.

Stream fishing( went up on Eagle Creek this AM with youngest son) for fall silvers we lost some rigs, but due to hard snags...not the fish we got on and played and landed.

I like playing with learneing about knotwork and ropework for a variety of reasons and purposes, but any well done properly applied knot that works at 100% of the line's test will do fine..
Get out there and fish..:) Jim
