After reading the posts on knots to attach flies or lures I decided to do my own unscientific test. I had a spool of ten pound test mono handy so I used that. I used two 2/0 hooks. I tied a Palomar knot to one hook. I tied a Pitzen knot to the other. I put the line through the eye of the hook twice when tying the Pitzen Knot. (the Palomar is by nature a double line knot) I made three turns down the line with the Pitzen Knot. The distance between the hooks was about two feet. I tied four of these. I held each hook with pliers and pulled with a steady pull until something broke. The Pitzen Knot broke the Palomar Knot all four times. When I when through the hook eye only one time for the Pitzen Knot the results where about equal for the two knots. I am making no claims other than what happened with my unscientific test. I hope those who read this will do their own test to see what happens.
