Probably spend the first 2 days building up your swim, getting the carp feeding, and then starting with the setup you ended your last session with, e.g. 3 x 18mm boilies. Why go through the small ones all over again?
Its funny cos i've been thinking about this exact same scenario Gert, at my local dam. problem is, its not 4-6,5kg carp thats the problem, but the 7-11kg carp that i cant get past. One option is 2 x 30mm baits and as the session progresses to reduce the amount of particles, and increase the amount of big boilies I feed....
