Ok I see...well...tiger nuts fished on a hair rig and running leger would probably sort out the bigger fish.
If you can see the fish, what about float fishing or freelining paste baits or naturals like a bunch of worms. Even on the most pressured waters, this tactic can fool a few fish.
It is still possible to get a bolt effect by fishing a hevvy lead and a very tight, clipped up line. Even though the lead is free to run, the clipped up line on the rod sets the hook. Maybe this is a way round it. Instead of boilies on the hook, look at tiger nuts, chickpeas, hemp, large pellets etc.
Hope this helps
