Braid can be the kiss of death for a fish in snaggy waters as the braid will most likely cut into underwater branches rather than "flow" over it like mono can.
Use decent strong line, I use 24lb 0.35mm control mono from pbproducts and can honestly say its the best line I've used in 30+ years of fishing.
Stay locked up, reel drags tight, tight lines and absolutely no baitrunners.
Strong banksticks or even better a goal post set up (as shown below).
Never a rod pod, these can get pulled over by an angry carp.
Be on your rod within seconds and use plenty of side strain in the opposite direction to the snags.
Most importantly of all, use SAFE rigs, no leaders of any kind. Especially those so called "safe zone" leaders. They simply are not safe in snaggy areas.
Ideally use hooklinks weaker than your mainline. I use either 12lb or 15lb hooklinks.
Use strong hooks, continental style hooks have a heavier gauge wire and are less likely to open up. Banktackle.co.uk continental hooks are superb for hit and hold type snag fishing.
Anything else, just ask and I'll try to help.
