Don't know if you have one or not, but a good locator that has GPS and a detailed lake map (like navionics premium east that has 1 foot increments) will increase your trolling catch rate. Look for the humps, underwater points/ sandbars near deep water, or follow creek/river channel edges, and any of the local brush piles you know about. Surprisingly, with B&M trollers and running minn-kota, I have found I lose very few baits. We get hung up, but by backing up over the bait , are usually able to yank it free. I mostly run 300's and seem to do OK. And trust me, there is something to the red hook thing on the bandits, and wisely that is why their crappie line of cranks all have red hooks. This process seems to work well in the middle of the day if you can stand the heat. Hands down, my favorite way to fish down there post spawn. Sounds like you are getting all the right equipment. You will have a lot of fun doing this.
