Hi Tony,
Never fished this length but as general starter for the weaver its a feeder chuck half to 2/3rds across with a 50/50 mix fishmeal/brown crumb darkened off,add very few freebies (10 maggots/pinkies) bites will come quickly but after a few fish things will dry up,a couple of quick bomb chucks over the top might get you a couple more skimmers,especially if its carrying a tinge of colour.
A pole line can be fed at 10m for roach and odd skimmers,same g/bait mix but keep cattying 8/10 maggots/casters over the top,mid match its possible to catch a few roach or small skimmers when everything else is dead.
with 2 hours to go i would try the tip line again, usually you can pick a couple of fish up quickly but it will die on you again after a few fish,now chuck the feeder down peg of were you started filled with chopped worm,this can pick off a couple of better bream late on as they seem to hang off your earlier feed,also if its rock you can often pick up a couple big billys down the side on the chopped worm.
I am no expert on the weaver mate but i have fished a couple matches on it last year and this was what we worked out.
Hope this helps
Pete
