I was part of wulac last year. I will tell you a bit about all three pools...
swan pit- lots of carp in here. luncheon meat, maggots, corn and halibut pellets pellets all catch carp here. To avoid roach and skimmers luncheon meat or pellets should be used. Sunflower oil is also great here, try meat or halibut pellet soaked in it..
Church pool- best fishing is from may- mid july (too many lillies in august). luncheon meat produces best results.
Tong norton mere- maggots used regular on this venue, pellets soaked in some kind of mussel or similar additive. Good results can be had if you put the time in here. Fish towards the end of the mere by the reeds and cast over to the other side. Carp seem to go there.
