agree with the top message. if you can get on a runs water and have succesful results over a measured period of time (try your own bait against a proven catcher) and if your happy with the results get on your target water and give it to them in places you know they visit. if you keep trickling it in and they accept it the results should follow but don't worry if it doesn't happen overnight. introducing a new bait can take time for the fish to accept it but when they do you should reap the rewards. rome wasn't built in a day!
