Thanks to all for the advice - we had a good day out on Friday, although the fish weren't too obliging.
I had 32lb - 4 carp on the method, 2 carp off the top on bread and pellet plus 3lb of small roach and bream on maggot.
A couple of others were pursuaded to buy "bagging wagglers" and managed to catch the odd fish with them.
Everyone enjoyed the trip and we are now planning another for September.
