this seems like a very simalr situation that im in carpholio ,as you no find a bait they like, find a location ie clear spots and aply the bait well topping the swim up rather than unleashing hell from the word go its,maybe extreme but i try to count boilies that have landed on the money and when i get a run ,either im lucky and my boilie is first to have been eaten but i usually try an work it out about half way point ..example 100 baits on the spot ,get a run an fish then gradually put 50 baits out to bring numbers up again ,,just a thought, soon be particle an fake bait time ...... or greeno's time .... its all about mantis gold
