Hello I'm going to a local canal sunday to fish for roach, perch etc with my fishing buddy. As I live very close to where we r going I was going to pre-bait the swims is this a good idea we will be fishing with bread and maggots (pinkies) so I was going to put a bit of Blitzed bread in tomorrow is this a good idea if so how much should I use and any other ideas for pre baiting.
