Throwing the plug all day without a follower would be pretty brutal. I think most of us would pick up a jig or a worm after 6 hours of trout hucking dead water. You can usually expect at least 5 followers per day, sometimes more (hundreds). As for bites, 5 trout plug bites a day would be excellent. Typically you can expect 1 to 2. 3 would be above average.

It's good that you decided to throw trouts more, but don't limit yourself. You can get burnt out if you throw trouts every day for a week without a follower. If nothing's happening after a few hours, pick up another rod for awhile. I would suggest throwing trouts every time it gets windy. If it's calm and bright, do something else cause your chances of trout plug fish are pretty slim. Focus on windy afternoons, early mornings and late evenings.
