Best knot...backing to main line

[das speck hunter]

I was always taught to use either a blood knot or surgeons (which I dont like cause it's tags seems to grab the main line). Would an albright be better for this application? Or what kinds to yall use?

Dont know what you call it, but I cinch 3 loops and pull it tight. Works for me.

i always use the blood knot . even tieing braid to mono

I use a double uni knot. It's simple and works with all lines.

Double uni-knot for backing to mainline with similar diameters. Easy to tie, small diameter and has not failed me yet.

Agreed. If you wanna have some fun though go learn the GT knot. It's also called the FG knot or the Sebile knot. There seems to be several slightly different versions of it depending how fail proof you want it. For saltwater where you need knot perfection for fighting brutes like tarpon, sharks, king mackerel, and other fish that really can severely test fisherman and tackle alike. There isn't a stronger line to line knot. I use the uni to uni most of the time, but if I'm going for biggies I use the GT. It is a pain to tie. It goes through guides better than the uni to uni too. There are lots of videos teaching it.

For me:
Since the backing line is there simply to make the spool's arbor diameter larger, and (in most cases) you've spooled on a sufficient length of new filler line, and will likely never have enough line out to reach the connecting knot, or will replace the filler line when it gets low (from breakages) or starts to deteriorate from age ..... most any knot can be used. This "backing to main line knot" shouldn't get exposed, even after letting out the greatest amount of main line that you'd ever use.

Generally, I pull the two tag ends together, side by side & make a loop, then run the tags thru the loop twice, then wet & cinch ... then trim the tag ends as close as possible to the knot. I've never been "spooled", nor have I ever let out enough line to reach the knot .... so my concerns have always been about the knot(s) that I tie my baits/setups onto the main line with. A lot of people are concerned about the possibility of being "spooled" (having a large fish pull off enough line to reach the backing or spool) ... but, I'd be more concerned with the condition of the backing line, than the connecting knot, in that scenario. Unlike the spools of line that you have at home, stored in a cool/dark/dry place, the backing line has been in the elements ... subject to heat & cold, getting wet & drying out, and possibly even getting some UV damage. That's why I totally replace the entire reel spool, about every two to three years, with either totally new line or 1/2 with seldom used line & topped off with new line.

Uni to Uni or Blood Knot. I don't see much difference in the trimmed tag ends. IMHO

I use the double uni with good results, and it goes through the guides easily. Hank Parker stated in one of his shows that it's his choice also. If he can use it in Mexico on those large green fish, I believe it will hold up for me.
