I often use the first night of a 2 night trip as a recce night too, figure out where they are for the next night.
Tbh at this time of year id be fishing them all on the deck over bait. Regards depth id be looking to put myself anywhere I see signs of carp.
I use chod hooks for chods and a big old size 6 wide gape for zigs. I have used chod and curve patterns for zigs too when I've run out of gapes. Tbh I'm less fussed about patterns for zigs than I am with rigs that count on good mechanics.
