Yeah, a little hard to sort out. It was either show the last bit up close, or show the whole thing but not in detail, so I went with the first option because I figured it would be better to show how the braid pulls up on actual line. Missed the focus slightly on the real knot (theres about 2cm of focus, and that was the max i could get)

Must be a browser thing. Embedding works fine on mine. I added a link so you can still click to get to youtube (where you can select HD too)

Short answer: Improved albright to single line braid, yes, definitely. To a bimini in the braid, I havent checked, but quite likely (for some line diameters more so).

Long answer: One thing that frustrated me with albrights is that you need to tie them well and pull them up well or they fail well under. Particularily between a light braid and a light leader where it can cut through with little pressure. Larger leaders can slip if you dont tie them right as well. 

The GT knot has the advantage of being a knot where if 'it looks right' its strong, while an albright can 'look right' but be weak if tied incorrectly, and can be very hard to pick up if its tied strongly. Its very very hard to tie a weak GT knot accidently (as it will be obvious its not right).

If you already have a bimini, the GT doesnt take any longer than an albright anyways, and it has the advantage of an upwards facing tag (better for casting) and is more reliable.

As for knots that 'havent failed'. I've tested all the knots i've used with scales so i'm confident that they have a minimum rated strain. Fished with 25% drag, a 50% knot will not break under normal use, but when you get the fish of a lifetime its a different story (or have to apply the brakes for a demersal or you get your line caught over the handle or something). Also, most people will have to bust off when snagged up or popping an unstoppable before you get spooled, so a strong knot can be quite useful in those situations.

Kinda like having a old VW on the freeway. It can still get to 100, it hasnt failed so far, but its a different story when you have to push it faster ;) At least, unlike cars, high performance knots are free ;)

All in all, its up to the angler, but if you want to learn a GT knot, at least theres a video ;)

If you cut the leader just below the braid, you can often pull the 'loops' off then slip off the mono knot. I heavier lines, bend the braid double back and cut through the mono with some good scissors and it comes off very easy (just gotta cut the knot right).

Again, a well tied albright ;) (but even then, its not as good as the GT :p though it is a quite reasonable knot if tied well)

Look up the tight line TV on youtube, Fishead have done vids for PR and FG knots.

Yeah, didnt figure out how to mute only that bit. When I played it on my computer I kept looking around for my phone, it sounded exactly like it (hence the note).

Yeah, ironically I use it for almost everything except GT fishing. Perhaps it was around before the PR and FG knots became popular? Certainly in heavier lines, the slimmer knots cast a lot better, but the GT knot works really well in light lines (down to 4lb). Plus its easy to tie, comparitively quick and can be tied on a rocking boat. No one knot will be best at everything though (but this knot didnt have many vids unlike the PR and FG).

Works fine for a wind on, however, if doing a wind on for trolling I will usually do a an aussie plait in the mono, then connect the braid to the mono using a similar method to the GT knot. I.e. you leave the mono on the spool and you pull the braid loop through the mono loop, then drop the mono spool through the open braid loop like the GT knot and drop through (5 or 6 times) then pull the knot up (have to be careful it doesnt slip up around the mono loop). See link. Puts less strain than a catspaw. Goes through the guides perfect on a fast fish. Lower profile and less snaggy than a GT knot. GT's are still good for casting, and still work fine for leaders while trolling. If you're knot is out of the guides anyways, I would just use a GT (much quicker). For 100m of topshot I would go the aussie plait/ted donelan.
