Not sure what you mean by this buddy.
If you have to drop the lead then go for the MCF Dumper lead clips, they're great for zigs. When you cast, whack an old pop up in pva mesh on the hook, it'll add weight to the hookbait and prevent tangles. Also, don't use any tubing/leader etc, go naked straight to the lead clip, prevent tangles even further. Use the longest anti tangle sleeves you can find too. Fox do some good'n's.
As for the fox/korda systems, do you mean the adjustable systems? I avoid them unless I really need them, they're not very friendly to use. If your zigs are 12 ft + you need them however. @nigewoodcock on here posted a great tip for these - when you hit the clip, don't feel the lead down, just let it fall naturally. Not sure how this works but it did work for me. Tangles stopped. Great tip.
