I'm going to have to agree with Raul and say that a mix of good topographical map reading paired with electronics is key. Take out the map and identify several (5-10) spots you think would be good. Then it's just a matter of hitting all the spots and using your shiny electronics. A process of elimination.

Those turtles just never learn do they? ;D

It may also be worth trying out some circle hooks. I'm fairly sure Gamakatsu makes some good ones. It's a little bit harder to rig a senko on them weightless and weedless, but those hooks are made to avoid guthooking.
