There's no shortcut for putting in time and research unless you happen to have a bud that knows your lakes like the back of his hand.
If you're catching dinks, your presentation may not be the problem at all.. you're likely just not on top of big ones. Be mobile. Try different spots and if that doesn't work, try different lakes. Where I live, there's several lakes in close proximity to my city that contain perch. But pretty much all of them contained stunted populations so it doesn't matter how skilled of an angler I am, I'm going to catch 3-6 inch perch.
When you're getting skunked, what is your flasher telling you? Nothing down below? Move. If there's plenty of fish around, keep changing your presentation until something works.. go bigger.. go smaller.. jig hard.. twitch jig.. bottom bounce.. do whatever you have to do. Sometimes it still won't work as fish -can- simply be inactive.
