Here's a nice little trick I’ve been doing to the boilies before using them that seems to work a treat...
I air dry them for 3-4 days just giving them a jiggle round every day or so, then the night before I go I transfer them to a bucket then add about 50ml of Kray & Krill dip to it and shake well. By the next day they have taken in all that goodness and are ready to release it all again when they are in the lake.
I do this with the hookbaits as well but repeat the process a few times air drying, coating in dip then once they have soaked in the dip air drying again. It's amazing how much you can load into these babies.
Good Luck, Mark Murray
