Never use the things, I hate them! When I did (briefly) try them I found they consistently failed to hook up some rod-wrenching bites. My other gripe is that if using a rotten-bottom length of weak line, this had a tendency to wrap itself around the rig body on the retrieve. So the sinker was then fouled on the rig body and if pulled into a snag with a fish on it was in front of the fish, making loss of the fish more likely. I prefer to have the sinker trailing behind, so that if it does find a snag it's more easily broken free - and if it's more or less at your feet (as sometimes happens) the fish is easier to get to, rather than being several feet behind (perhaps over a ledge) where you can't get at it.
For these reasons my go-to rough ground rig is about 3ft of 50lb Maxima tied to the same swivel as about 4ft of 80lb rig-body, which has a rotten-bottom length of weak line (usually 15lb Amnesia which can be snapped easily, although I'll sometimes use stronger if I think I'm throwing away a few too many sinkers!). Far rather lose a few weights though than fish, especially as I fish a lot of comps. If I need a clip-down rig then it's much the same except I'll make rig / snood length the same and attach an Imp, with a rotter & weak-line set up as before.
tried same set up,,... prefer... shorter hooklength than the main body gaz.
fish on same actual level as the sinker then innit.
