Joining Fluorocarbon To Mono Backing.

[OroBass]

So I'd like to have my worm rod filled with fluorocarbon but have like a 70 yard cheap mono backing. I've been thinking the double uni will work. I will be using about the same weight line. What would you guys do? Please no info on leader knots as that is no what I am doing. So in your response please remember some knots require the leader end to be passed back through the knot which would be unrealistic for my application. Thanks guys.

I use the Alberto or Albright knot to join lines, the knot is small and the joint is very strong.

I use the double uni.

Forgot to add, after tightening I add a drop of Krazy Glue.

I use somewhat of a surgeons knot, but if your ever fighting a fish and you get down to that knot you have bigger problems anyway

[Catch and Grease]

I use the double uni for attaching backing as well...

[Marty]

CD1542 nailed it. It really doesn't matter. In many years of using backing I haven't gotten down to the knot, even when I've hooked hard-fighting carp.

[OroBass]

Good to know. I'll stick with the double uni and a dot of crazy glue. Thanks guys

How do you guys know how much backing to use

Just depends how much line you want to save... Just be careful not to have to little main line to where the backing shows after a long cast/pulled drag...

I was just spooling up my 1st baitcaster.  I tried a double uni to go from 10lb mono backing to 30lb fluorokote mainline.  Found the knot to be too large because it caused a bulge in the spool.  Ended up spooling straight fluorokote without backing.  Any ideas on a better knot or something else I might try?

I'd just tape the backing down, and tie an arbor knot.

Nice idea.

I used a simple blood knot for decades join top shot line to backing.

on two lines of similar diameter uni-uni is the way to go. The modified albright will make it unnecessarily big.

The bump from many knots bugged me a little, so I decided to try a three-turn surgeon knot. You have to pass the spool or the reel through a bigger loop than usual, but other than that it's easy, and it is the tiniest knot I could find.

Same.  I don't make as many wraps, making the knot smaller.  The idea is this knot will never come into play, therefore I don't need it to be the worlds strongest connection knot.

This line calculator for stacking lines of different diameter is very accurate.  

 

And here's how clean you can make an Allbright knot - I've shot these knots through fly rod snake guides for 40 years.  

The trick is to roll them as you're tightening - remember the direction from when you made your loops.

The issue isn't shooting the knot through snake guides, it's the bump it puts on the spool that you can feel through 100 yards of line.

Shouldn’t feel a blood knot with 10 yard of line covering it, I can’t.

ok, and this knot is 1/3 the volume of a double-uni and Much stronger - with double-uni, the thinner line can cut the thicker, even if they're both mono.  

 

another choice, you can go loop-to loop.  A perfection loop in the mono, and a double surgeon's loop in the braid large enough to go over the reel to complete the loop connection.  This isn't as strong as the Allbright, though.  

[J Francho]

See my post above.  Tape the backer and tie an arbor knot.  It literally as simple as that.  I don't know why we feel the need to complicate something that won't ever see the light of day until you strip off the top shot.

I solved this for myself by using cheap 50 lb braid backing on all of my reels. Just a 4 wrap per side uni to uni connection to the mainline. It reduces the bulk of the connection knot. I use two small squares of Super 33 tape placed on the spool 180 degrees apart after I've cinched the arbor knot for the braid backer. No spool slippage and no bulky arbor or connection knot.

[J Francho]

I must be the only one that just leaves the old line (fluoro, braid, mono, whatever) that was already on the reel as backer, and spool up the new stuff on top.  Obviously, I strip some of the old line.
