    Any one use San Diego Jam Knot for line to line connection similar to double uni knot? I tried it last night and it seemed it worked. But never heard people mentioned it.

    Thanks

    Nope. Does not sound like a good idea. The San Diego is a slip knot, that means the harder you pull the tighter it clenches the connection possibly causing the lines to cut each other. Also, it will be a very big knot that will not easily pass through guides.

    I use a Bob Sands in most cases, it depends on what type of lines you are joining.

    sunk it
    That would be a big knot, single is pretty big. If it’s from mono to a short piece of floro might big good as a stopper for a small sliding egg sinker. Don’t know if it would be a strong connection though

    I had bad experience on triple surgeon. I mainly use double uni now.

    3x joining what pound mono-fluoro lines - how many times was the knot reeled over the guides (or stressed) under load

    2x on heavy line 80#+ what I was told, use 3x for lighter line
    you need a proper cinch (like any fishing knot)

    surgeon knot is a staple of seasoned big game fishers - maybe it was a bad tie (bad cinch where I would start looking) - I wouldn't be so quick to write it off - examine it closely and pull test it before you send it over the side (like any fishing knot)

    but I am a fan of the San Diego jam knot (for 50-plus mono/fluoro to hooks, lures...) (even double San Diego for heavy braid) you will probably use less wraps on the heavier lines - whatever you can properly cinch

    Which one? Too many....
    With a back-to-back San Diego, whether single or doubled, the loop of each knot is directly around the loop of the other. They can cut each other.

    Whereas the back-to-back uni, the multiple coils of each knot are against each other. To visualize, pretend you are holding a baseball bat with your two fists (like you are about to swing at a pitch). Your two fists against each other are similar to how the two uni knots press together. It won't cut itself.

    The long-range crews will use the uni to uni for quick repairs (even with a fish on the line). The surgeon's will not work in this situation (line in the water to the line on a rod). But....as stated the surgeon's is great for attaching a leader.

    the thing to do is just Google ,the RP knot,
    and I add A half hitch on both ends , and it works great,
    Mono to Flouro , I use the simple Seguar knot ,

    For whatever reason, I've had zero failures with the double uni, but a few with the RP knot. I really like how the double uni puts all the load on the wraps, and not so much on a bight.

    Wet it good and the knot will pull tight.

    ...the back-to-back uni...

    Interesting, I never looked at this knot (back-to-back uni AKA double uni knot)

    are you saying it is as least as trustworthy as the 2x-3x surgeon's knot for 50-100-lb mono/ fluorocarbon fishing line?

    Hi GB,

    If you go back to the original post:

    "Any one use San Diego Jam Knot for line to line connection similar to double uni knot? I tried it last night and it seemed it worked. But never heard people mentioned it."

    he is asking about a comparison between back-to-back San Diego, and back-to-back uni. The context was not specific (to leader attachment, or broken line, or...)

    But specifically for leader connection of mono to fluoro, my sense is that more experienced long rangers will use the surgeon's than the uni/uni. That is certainly a Coke / Pepsi argument (personal preference). I've never seen any actual test results; that would be interesting. But a well-tied uni/uni is very dependable. I use it for certain connections. But also use the surgeon's. Love the San Diego for attaching to hooks, but I would never use a back-to-back San Diego for line splice.
