You definitely need to get a guide. There is too much water to know, and, when I was guiding, the main thing I brought to the table was knowing where the fish were at the time and using the right tackle and techniques to catch them. A good guide should have all this, and without it you are lost and may not find yourself. If you are bobber or float, make sure you use a floating line (like one of the braids). Trolling is easy. Use mono and a long rod (8ft. or better if you have it)and just set your depth sounder on the 8ft. contour line on the South facing shorelines. Use a 4/0 Trueturn hook and free line with the shiner hooked only through the lips (not the nostril) so that is comes off when you set the hook.
