    Strenght of leader vs main line

    When using fluorocarbon to braid, what are the differences between the strength of the two lines used. (example = 40lb braid to 15lb fluoro)

    I'm not sure what you are asking...

    the difference in strength between the two would be 25lbs but I am willing to bet you can do simple math so we need a little more explanation lol

    I would guess that he wants to know the maximum recommended difference in lb test rating between the braid and the fluoro or what lb test most people use for each line when attaching a fluoro leader to braid.

    Main line braid should always be the same or heavier. Example; 10lb braid to 6 or 8 lb leader. 30 lb braid to 15lb or 20lb leader.

    Not sure if he’s asking this but I have an alternative way of looking at it.

    You want to match the diameter of the two lines as closely as you can. In theory, 20 LB Braid should have the same breaking strength as 20 LB Leader. But one has a diameter of 4-6 LB line and the other is the Diameter of 17-25 (depending on which lines you use). This will cause several issues.

    General rule of thumb is my braid will always be a higher breaking strength than my leader, but I match the following LB Test Braids with the following LB Tests for Leaders (there is a bit of overlap):

    - 8 to 10# Braid with 4 to 8 # Leader on Spinning Gear only
    - 15 to 20 # Braid with 8 to 10 # Leader on Spinning Gear only
    - 30 to 40 # Braid with 10 to 12 # Leader on Spinning or Casting Gear
    - 50 # Braid with 12 to 17 # Leader on Casting Gear only
    - 60 to 65 # Braid with 20 to 25 # Leader for Flipping Sticks Only

    Anything over 65 doesn’t get a Leader lol.

    I'm more concerned with matching up line diameter than poundage when it comes to Flouro leaders..
    If you get too big of a difference the knot won't hold as well..

    I've never put any research in it but you still have a leader however long that is really light line so what is the benefit of the braid? The fish can still break the leader with it only being 6-10 pound test line.

    Better feel and better hooksets on longer casts are the main benefits. Fish can and will break any type of line of most every pound test but there's things you can do to counteract it and limit the number of occurrences. Propper rod power for the line you're using and drag settings are huge in this case.

    How big of a difference should there be if any?

    Less line twist, easier handling and better feel in deep water or long casts than going with straight Flouro..Also braid ends up being alot cheaper because you don't have to replace it as often..

    The best way to say what these guys are saying is you want the diameter of your floro and diameter of the braid to be close. Forget the pound test and look at the diameter. I think thats what your asking anyways.

    In the past, when I Carolina Rigged, I always used 14 lb. Super Silver Thread for the main line, swivel of course, and a 14 lb. Berkley Trilene XL leader. The leader always broke first, and I never lost the swivel or weight/ticker/bead, ever. I did even more "light C'rigging" (guys around here called it "Splitshotting", but it wasn't) with 8 lb Excalibur to swivel and 8 lb Trilene XL leader, and didn't lose that many weights.

    I think the OP is asking about what sort of differential one should use, to be sure that the leader breaks first. A couple weeks ago, I was rigging up for C'rigging again, and again used my SST 14 lb test. Was going to use 10 lb Excalibur leader, but came across some 12 lb South Bend monofil, so used that. After I tied it up, I dug out a micrometer and discovered that the 14 lb SST was smaller diameter than the 12 lb South Bend. Since diameter is a major factor in strength, I'm rather expecting to lose my weights soon. I'm going to use 10 lb Excalibur next time, or maybe SST if I have any.

    The C'rig is the only baitcaster setup I use a leader on. I use straight 10 lb FC on a Chronarch for Shakyhead and like it a lot, but not that sold on the FC part...might change to copolymer of some sort. On my DS combos (spinning), I join the braid mainline to the FC leader with a swivel, and like it.
