Hi Jeff,
I have not tried much night trolling on P4. I have noticed that my favorite trolling runs on Pepin generally produce best between 9:00am to about 4:00pm. For some reason the later I get into the evening while trolling, the slower the bite this time of year.
But maybe thats just me and I need to make some other adjustments to stay on them…. Could be different in the river/backwater channels too. I’m interested to see what others have to say about this topic….
Tight lines!
