I use the "Skip's Clinch"(Skip Morris) which is just another pass of the tag through the final loop made of the improved clinch. Works well and haven't lost any to a slipping knot.
Regular improved clinch knot for the swivel to leader to hook.
Personal experience is that the thicker diameter mono doesn't clinch too well
And always check your leader and the mainline a feet or two above the weight for abrasion after a snag.
I also find that if you "point" your rod in the direction of your line(as opposed to high sticking) you can "feel" the rocks, so there's no confusion between a snag and a fish, limiting those imaginary hook sets. Just make sure to reel slack in your line to 12oclock(slowly) in case you're casting upstream, that'll reduce snags.
