It's not winter yet, but why not get a jump on winter arguments.

 

Why do they want the braid to be the weakest point? Is that explained later? I only made it 4 minutes into the video. I can't watch the rest with that question in my mind. When fishing, I want just the opposite - I want the leader to break before the braid.

 

They're using 20# braid with breaking strength of 40-something pounds, and 60# fluoro leader. It seems like that might affect the effectiveness of how well the knot is tied.

The test is geared more toward what many would consider an average saltwater fishing scenario.  You are correct in assuming most of the time bass fisherman will be using braid that is stronger than the leader.  Of course changing to stronger braid over leader, could completely change the results.  I would be surprised if it changed the order of which knots were the strongest.  The actual percentages may change, but which knot is stronger I believe would probably be the same.  My personal experience with the same knots is similar to what the tests in the video show.  I don't bother with FG or PR knots when bass fishing but do use them exclusively with larger salt water leaders.

 

Everyone has their favorite knot, and who doesn't like to jump in to a good knot argument.  The one thing I found interesting is each knot broke consistently at the same location, which was different for each knot and  even the FG is not anywhere near a 100% knot.
