If you sense there are lots of fish in the swim, it is best to cut back the amount you feed. Feed just before you cast but scale this back to three or four pellets so it forces them to take your hookbait. If there aren’t many fish in the swim, step it up to 10 pellets to make more noise to draw the shoals. If there is any wind, make sure you sit on a swim where the wind is on your back. This will mean casting is easy.
