Imo pulling the lead back is the kiss of death. There is a significant chance you'll foul or even blunt the hook, regardless of what substrate you're fishing over. The obvious answer is to go to a heli set-up with the top bead set to cope with any of the substrates out there. You mentioned that everyone is doing this - there is a reason for that.
By all means keep your options open in terms of differentiating yourself from others, but make sure you have the very basics (presentation of a bait to a carp) right first.
You're over-thinking it imo mate. This water sounds tricky enough without coming up with new problems. Keep it simple. The focus needs to be on presenting a bait to a carp. If you spend the coming weeks trying to do that whilst watching the water like a hawk, the carp will give you the clues you require to fine-tune your approach in terms of location and tactics.
I think you're getting ahead of yourself by creating your own problems ("the silt furrows", "the fish don't act right", "the weather doesn't act right", "chods are for sheep", "it's too far/windy", "the water pressure....", etc, etc....).
Whack a couple of baits out where you have seen signs of carp, sit down, watch, and use the info that nature will give you if you look hard enough. Keep it simple. Enjoy it.
And get rid of the Fish-Spy lol. After all, that is what started this confidence issue you seem to have. No electronic device can ever be as effective as an angler tuned into the natural environment imo.
