Crappies primarily, but we have property near lake superior in Two Harbors. I fish the big lake as often as I can. I get most of that itch scratched from the breakwater in Tow Harbors but a friend and I also have a boat rigged for trolling the big one too. That purple is a dynamite color on Superior at times. Any purple combo for that matter. In the fall we troll slicks that can be five or six miles long and we use purple for that a lot. We are not fishing deep in a slick, maybe five or six feet and on a long line of about 200 feet. I have some purple Yo-Zuri sticks that are great for this along with some Wally Divers. Your purple/clear would be a great candidate for that purpose.
Where are you at? Which state? Did I see Iowa somewhere?
