can it be done and is it advisable to?
reason is I have some 20# on a spool and the spool is maybe a .25 the way full and I would like to fill it up with the remains of some braid(same type). basically I'm cheap and if I can get by with using what I have then so be it but if I have to bite the bullet then thats what I'll do.

and finally what knot to use to bend the two together if I do it?

thanks

A bloodknot will almost disappear if you get it right. Difficult on braid ( for me, anyway.) My second choice is an albright. Don't skimp on the wraps on either one.

The cheap bass turd I am....I was successful with Uni to Uni on my free tiny samples of Spiderwire stealth......

Albright is what I use, works great

bloodknot or uni to uni. freekin' uni knot is the balls.

Albright for sure....many turns

The Albright makes me nervous in a braid to braid connection. The wraps can slip over the doubled over line if it isn't tied VERY carefully and snugged down completetly. Traditionally the Albright is used in situations of joining lines of fairly different diameters. The fatter, heavier line makes a nice bump at the top of the knot the lighter, thinner line can butt up against. Lines of a similar diameter (especially thin braids) negate that quality of the knot. Bottom line is I would NEVER send a customer out of the shop with 2 sections of braid connected with a Albright. It may work, but I'd be constantly worried they would come back pissed after losing a fish of a lifetime. Using a lock on an Albright will help the cause. (http://www.fieldandstream.com/fieldstream/outdoorskills/article/0,13199,1180411,00.html) But I still much prefer a uni to uni knot.

I've been using the uni to uni for a long time. It works. For everything short of big game it will do the job. Although instructions generally say it is only for combining similar diameters, I've found it has no problem joining something like 14# Fireline to 30# Fluoro. Last years inshore tuna season proved that beyond a shadow of a doubt. Use a few less turns in the fluoro and at least 6 turns in the braid. As a braid to braid knot it's my favorite by far. 6+ turns on each side. Be sure to snug this knot down properly and completely before cutting the tags. The only failures I've seen come from slippage. This is a knot I trust completely if I have to connect braid for a customer in light tackle or surf outfits. Only way to really make it stronger is to tie Biminis before tying the knot. Much bulkier though for such a minimal gain.

That is interesting Pete, I have never had a problem but I see where a Uni is better by design. I hauled in a 44 pounder a few years ago with a albright to albright, if I would have lost that fish I would have died right there hahah. Usually I just re spool if I break.

Off topic, but how much is a spool of lead core going for? 45% 100 yards.

It's not that an Albright doesn't work, in fact for a bunch of applications it's one of the best knots for the job. I'm just not sure it's the best for this application. There's a lot of people using it without issue though so it can't be all bad. Most of the failures I see with an Albright are under shock conditions. A slow, even pull doesn't necessarily show the weakness. Pop an Albright with a few quick shocks and you can sometimes get it to let go. I always shock test an Albright I tie. If that tag end slips through or the wraps manage to get over the tip of the knot it'll completetly let go.

I'm at home today so I'm not 100% sure on the price of the lead core off top of my head. I think it's $11.99 though.

alberto knot. its a modified albright. very stong and low profile.

Uni is the one I have used without anything coming apart ever on a braid to braid or a mono to braid setup. Its really a trip when you land a fish and your knots stay together.

I always equate the albright with my flyfishing.......

Whatever knot you use, add a tiny drop of superglue to middle of the knot. That'll add insurance. Wrap a dime sized peice of wax paper over it so that you don't need to wait for it to dry completely before finishing winding.

I never use glue in the field, but find it helpful when splicing lines.

I use uni-to-uni connection for braid to braid and mono to mono, but have recently started using the albright for mono leader to braid. Satisfied customer.

I use uni-uni joining lines..I don't like the blood knot because of the tag ends sticking out the sides . trim those too short, you may have a problem .. Albright,,fly line to backing

can it be done and is it advisable to?.

Yes it can be done and if properly constructed, such a knot will not significantly weaken the line.

For joining equal diameter braided lines the uni to uni is best.

For unequal diameters the Albright / Alberto is good but I have been using a short spider hitch in the 20lb and then to back to back unis. I use braid exclusively on my spinner bait set-ups and use a 20lb running line (Sufix) and a braid casting (shock) leader of between 50lb and 100lb depending on the set-up's duty. When using 80 or 100 the 20 really needs to be doubled to resist slippage.

Yes, it gives you two knots about 4-6 inches apart but they go thru the guides fine and I use Fuji LSCG SiC Lowriders exclusively on my distance rigs (20mm gathering guide).
