Default Loop to loop connection

When using a loop to loop connection do you have to do a full cats paw knot or can you just make a single pass through? This is for when using wind on's for swapping lures and debating using a bimini to perfection loop for tuna chunking as well for quickly replacing circle hook leaders.

Single pass works fine

Some time ago I asked myself similar question. I found different opinions on the Internet. To be certain I tested some connections that I was going to use. Below are results of this testing.

Tuf Line XP 30 (48lb ABS)
LtL to itself: 30.9

Berkley Trilene Tracer 40 (66lb ABS)
LtL to itself: 48.0
LtL to JB130: 69.6
LtL to JB130+3catspaw: 79.3

Seaguar Threadlock 50 (90lb ABS)
LtL to itself: 53.6
LtL to itself+6catspaw: 87.5
LtL to JB130: 85.5
LtL to JB130+3catspaw: 106.2

As you can see if you connect similar lines then loop to loop connection is far from being 100% strong. However when one of loops is made from much thicker line (Jerry Brown 130lb in my case) then loop to loop connection indeed is close to 100%.

Note also that there are two ways to make loop to loop connection, and one of them is incorrect and will result in very weak connection.

Wow, thanks for the data. If I am looking at this correctly it looks like the single loop to loop puts the connection very close to the absolute breaking strength? But adding a catspaw makes it that much stronger. I have very little experience with a catspaw but for a quickchange leader I am very slow at getting them apart and don't like the kinks in the line once the catspaw is undone to then re-connect it via catspaw again. Am I thinking too much into the catspaw?

Single loop to loop connection will be close to line ABS only in case when second loop is made from significantly thicker line. If second loop is made from the same line then loop to loop connection will be only around 70% strong.

I also do not like to make cats paw knot because it takes longer to make it and to disconnect it. Because of this I decided that in case when I want to use loop to loop connection my main line will end with loop made from relatively thick line. In this case simple loop to loop connection will be sufficiently strong.

Makes sense. Thanks for all the info and have faith in a single pass in a dacron loop to mono bimini.

Single loop works for me...never had a failure.

Glad to hear the success had with the single loop. Thanks for all the responses.

The correct method is called a handshake loop. It's considered a 100% connection.
