ok i have a question. There is a submerged island surrounded by deep water i plan to fish. I have no idea what the bottom composition is, but i know walleyes and muskies cruise the flats hitting minnow plugs in morning and eve. My question is, what should i fish the slope with and with what methods? should i troll the slope with crankbaits for wallyes or jig it?i dont know if this is enough info, if not, just ask.

oh, or should i work a skitter pop or other topwater over the flat and into the deep water to draw out the feeding fish?
