hehe, see i made a bit of a typo there, but you guys understood.
Doc, yeah i devised something similar with how i finish off at the end, also so that the knot/s can handle going through the guides better and for longer. i did this as the mainline to braid leader knot has to go through the guides, no way around that, and although i prefer having the one to the mono / fluoro leader stay outside the guides at all times, sometimes i'll make it a bit longer, eg. for when i know i'll be fishing between the bricks all day where one wants better abrasion-resistance and distance / big casts aren't as necessary, and i'll likely be trimming off quite a bit due to abrasion or changing terminal tackle...
Your opposing half-hitches sound even better, reckon i'll try it, but lately I've been finishing with two single overhands, then a final one with four wraps back towards the two singles - these i snug down very carefully so they don't overlap then tighten snug but not too tight as you describe, then just a drop of glue - so far no issues and lasts ages. and it also makes a nice "ramp" as you mentioned in an earlier post.
i check everything before and after most casts, but it's been ages since i re-tied an FG for any reason other than my mono/fluoro leader becoming too short from trimming with terminal-changes, from it getting roughed up on structure, or from it whitening with age (which to me means it's getting brittle).
bit off topic, but i am very glad i started using a braid leader a couple months ago - lasts ten times longer than thinner main line - the bionic finger abraded 50lb mainline quite quickly - every third/fourth session i would have to trim off several meters to get this weak section out, now i only have to replace the leader very occasionally and only lose 20cm or so mainline at a time, which is awesome - we all know the cost of braid! recently got a proper spinning / dropshot set-up and decided to do the same (25lb main, 50lb braid leader, 60lb fluoro leader) as i heard the casting glove will also wear through thinner braids quite quickly. On all 3 my setups the knot goes through the guides fine too, helps that it's braid to braid - somewhat more supple/soft than braid to mono/fluoro.
