if you were to place 1 grain of artificial sweetcorn on a hair thats where the real results lie, simply because it counter balances the weight of the hook and makes the whole bait presentation lighter (and not actually popped up) especially over ground bait when particles are getting blown all around by the fish sucking in and spitting out bait and when the carp comes across your counterbalanced bait it doesn't feel it go in until the hook is in the lip.

good tip there !!!
