Well, got a little bored tonight after cleaning up some of my fishing gear and decided to put some of these knots that we all swear by to the test, I only fish mono and flourocarbon, so I have no idea how any of these would perform with braided. The test equipment. bargain basement generic 12lb test mono cheap made in china 50lb fish scale a hook The method. tie one end of the line to an imovable object tie the other end to a hook with the knot you are testing pull on hook with fish scale keep pulling until the line breaks and read the number it broke at rinse and repeat one more time to make sure the results are consistant The contenders Improved Clinch - Touted as being a strong knot which retains nearly 100% of line breaking strength, yet is not perfered for heavier lines due to it's tendancies to try to untie itself..... personally this has always been my favorite knot for tying on swivels, and I've had good results all the way up to 30lb test, I use 6 winds regardless of line weight. The trick to tying this knot properly is after you've slipped the windings down to the hook or swivel eyelett, give the shock line one final tug until you feel the knot *pop*, the windings will open up a bit, just push them back down to the hook or swivel eyelett, and the knot will be far less likely to untie itself. For the test I used 6 wraps. Palomar - Supposed to be a strong knot.... looks like a strong knot, very simple to tie, and one of the few knots you can use with braided lines. Hook Snell - Ideally this should be a very strong knot since it is a type of slipknot and at no point strangle itself off as with an overhand(granny) knot, the only real problem I've ever had with hook snells is that they start pulling apart after a few fights, for this test I used 8 wraps. Double Snell - This is my own version of the hook snell, I was going both for more strength and less of a tendancy to unwrap itself(and it actually stays together pretty good), the method for tying this knot is exactly the same as with the standard Hook Snell, except you double the line over before you start.... since the line is doubled over you can't use as many wraps as you would with a standard hook snell, I used 6 wraps. The Results. Improved Clinch - The strength of this knot honestly surprised me, no matter what I tried I could not get the line to break at the knot, the break was always atleast a few inches away from the knot, not even a hint of the knot attempting to untie itself, this knot proved to be strong enough that it is the knot I used to tie off on my desk for the tests..... the line broke at 14lbs(but no where near the knot). Palomar - This knot surprised me as well, but for a different reason, it's actually alot weaker than it looks, both times when the line broke, the knot was left holding on with only one strand, so I have to assume that the knot itself caused the failure, it's still well within the breaking strength of the line however, and due to it's rediculous simplicity and speed with which it can be tied, I still believe it's a viable knot..... the line broke at 12lbs(point of failure seemed to be the knot). Hook Snell - For such a complex knot that requires a bit of practice to get it right, I'm a little disappointed with this knot, both times the line broke off right at the knot, not only is it hard to tie and has a tendancy to unravel itself after a few fights, the line breaking off right at the knot is also an indicator of the line being *choked off* at some point inside the knot.......the line broke at 11lbs(directly at the knot). Double Snell - Well, I guess it's back to the ol' drawing board on this one, it does hold together better than the standard snell, but suffers the same *choking off* effect and causes the line to break off right at the knot......the line broke at 12lbs(directly at the knot) Conclusion. Imroved Clinch seems to be the best knot for tying on tackle in =<30Lb mono(and probably up to 50 pounds if tied properly and the tag end left long enough), I'll personally be using it for everything I can from now on.
