I have tried most of the above and still had problems with line stretch after some hairy Bass had to be dragged from the surf,
didn’t happen all the time but when it did it meant I had to swap over rigs or use the rig as a flapper,
I use the Mustad bait clips below for some time but found all too often the bait wouldn’t release on contact with the water so I started to nip a little bit off of the curve and they worked fine,
Very easy to adjust, simple matter of pushing it up or down as needed, now I make my own and I have to say they work better then the ones I modelled them on,
Before I started to cut a little bit of the curve off I found if you leave a little bit of slack on your snood so the hook sits freely in the curve but wont come over the edge of it worked fine also,
I think these will solve your problem, there’s 2 types that I know of, 1 up 1 down,
in the link below they use crimps.. I use stop knots made of tubeing.
