Jack,
Don't be afraid of cranking the motor/speed up a notch or two even with the Sutton's. This time of year it seems most productive for me at least to troll things near the bottom and up at the top rather than concentrating on the suspended stuff. All of us are guilty sometimes of thinking every fish marked is a trout too Many times bass and other species of fish suspend and are not interested in our lures regardless of presentation. Usually if you can find pods of bait someplace that will pay off with fish if you are persistent.
