It happened on multiple occasions last week. On one, the fish pulled off the bank after 9 o'clock, but then around noon, I moved more carefully, took longer casts, and used the sun to help me find the dark cover spots in the shallows. I caught less numbers, but most of my 5+ lb bass came around 11-1. If I was better, I am sure i could have still caught numbers during those hours, but I stuck to the approach I was confident with to catch bigger fish (using jigs, swim jigs, and S-Wavers). I have read from many here on the forums who are much better than i ever will be who swear by the 11- 1 bite. I truly believe the biggest deterrent for big bass at that time frame is the fisherman's frustration and/or mindset (too hot, not enough bites, hungry, less focused, fatigued, etc.).
On one occasion, the jig bite slowed down real fast and the worm bite picked up and was out fishing the jig 4 to 1. The worm was catching more 3 and 4 pounders as well; however, tempting as it is was to switch; especially with it getting close to noon and getting more sunny and hot, with that much vegetation, i never feel like it is a smart move to go away from the jig in MN. While i got outfished in numbers and 4 pounders, I ended up catching the top three fish that morning/afternoon and i was in the back of the boat with the last cast.
