alright mate,
fished the pits quite alot,
depending what your after pits 2 and 3 offer the best chance of a run (my mate had a mid double common off the top on sunday on pit 2 while it was snowing!!)
pit 4 is bream, bream and more bream to doubles with a few elusive carp, then there is pit 5 and 6 with the biggest carp in the complex, 6 is easier than 5 but the biggest carp are in 5.
if you look on the a1pits website under the download section there are pics of 6 when it was drained giving you an idea of the bottom, features etc etc
good luck for the trip
