Well I be dam... the uni knot and the double uni knot were the knots my father taught me 40 years ago when I was 12. Actually these are the only two knots I use till this very day.
Thanks  The_Gaffer for your useful information.

@givella - make sure when joining floro to briad and using the double uni knot, you need to pass each line at least 10 times through the loop before tightening.  This will prevent the braid (especially) from slipping.

however as far as i know, the double uni knot isnt a knot for fluoro to braid. it will probably give you around 40% performance if not less.  good knots are tony pegna, PR and FG knots

@ganni - the 3 knots you mention I must admit I've never heard off.  However, one of the best forums on the net recommends either the uni or albright.

thats very true gaffer however there are probably a number of reasons behind this: its a much easier knot to tie when compared to the others, and an important issue might be that this post is over two years old and the knots i've mentioned are relatively recent knots

[The_Gaffer]

well, as I said, the uni knot is universally recognised as one of the best knots around, for joining mono to mono, and other variations, the double included, to join braid to mono.  Yes it is a fairly easy knot to tie, but then, no one gets browny points for making life difficult.  Some of the world's top charter captains use the uni knot and recommend it all the time.  Again, it's all down to personal choice, what works for you is alright for me, as long as my knots never fail or slip!  
But to say that the double uni knot is not a recommended knot to tie braid to mono, then that is blasphamy in any angler's book!

thats true, its all a matter of preferences!!  i always try to get the best out of a knot, no matter how complicated it can get haha

Gianni, in the beginning there was the uni and albright, then a number of variations spawned from there.
The knot you recommend as the Tony pagna, is not an original for this guy tony!!!...search on youtube and you'll find similar knots which have been around for years!!

Here's another variation of the uni knot, known as the double grinner knot, same principle as the double uni, but with a lot of twists and turns.

yes the grinner knt is a very good knot, read a number of good reviews about it

this is the one i use: http://www.youtube.com/watch?v=2e9XgPsWZao

[The_Gaffer]

great, so you use a variation of the uni knot, known as the grinner knot.

[ganni]

ahh good to know that you call that FG knot the uni knot... and yes typical?? hahai'd better laugh at this

[The_Gaffer]

Ganni - ma nafx, but whatever you're on, I want to try some!
I was referring to the grinner knot, not the FG.

Incidentally, just reviewed the FG knot, never saw that before, though I believe it looks like a very strong knot, especially since there are no knots tied on the mono, which usually contributes to knot failure.

Very interesting post baghira!

I use the uni to uni knot only when line diamaters are similar, but when diameters are different I prefer other knots.  This because imo the thinner line tends to cut through the thicker line.

I had written somewhere what I use but here it goes again: double the multifibre with a bimini twist, connect this with a brostol knot to a thick multifibre (0.60mm diam), then connect this to the fluorocarbon (0.60mm dia) with a uni to uni knot. 

I know its complicated, but never failed on the knots even when snagged.
