What are the conditions you are faced with? Are you fishing pre/post spawn, summer, fall? Is the water clear or stained? What's the main forage in the lake? Lots of weeds? Are you fishing from shore or boat? Do you have a sonar?
All presentations are effective at one time or another, depending on what you are faced with. I think a Jitterbug is an effective presentation - sometimes - but not at other times.
Thinking you are face with a Canadian shield-type lake; not very fertile, rocky and deep. I'd search points and inside bends with a wacky rigged 5" Senko for starters, if it's a summer scenario you are faced with. Or, if it's early in the season, you would probably be better off with a suspending jerk bait. Again....it depends. A little more info would be helpful.
