Do you truly want to know which knot is the strongest? Then experiment. There's a very good reason there are some many different answers to this one simple question.

Tie each knot and test it. Get a scale and record at what force it breaks. Do each knot five times.Throw out the high and the low, and average the rest. Do this for each knot. You will get your answer.

And I'll tell you which knot it will be.

It will be the one YOU tie best. It probably won't be the one I tie the best. Or the one Catt ties the best. Or the one Aaron Van Grigsmartin ties the best. YOU.

Another vote for the Alberto knot.

None whatsoever. The braid is so soft it makes no difference going through the guides. Doing the final half hitch by going through twice also helps lock the half hitches down, the longer tag end is just belt and braces insurance.

Cool, thanks! I'll try that next time.
