So the lake I normally fish has a good walleye population, but also really nice perch and gills. Frequently, they fish hang together, or, I will catch a good mixed bag in the same area. However, as the afternoon turns to evening, I get that twinge, and know its time to put away the small stuff and get out the 'walleye getter'. Not sure how I know when to make that switch, it isnt really an exact time, or when the sun goes down, etc....I just kind of think to myself....OK, lets go for the big guys.....When do you make that switch, if you do, or do you jig for eyes all day long.....
