I usualy go accross current during daylight hours,puting the boat above structure with lures below and behind structure,using boat angle and current so as to not loose ground down stream.If the bottom has rocks small enough to slowly crunch down stream using Hi-Fin Trophy Divers made of closed cell polyerathane foam,that bounce lip first over structure,I will also do this through deeper holes.But night time it is almost always dead slow going up stream again'st the current.With gin clear water I'm usualy going accross stream using the longest lines I can putting the boat as far upstream as possible and using a 100 lb Seaguar Fluorocarbon Leader,3/4 the legnth of my rod,placing only the crankbait and leader in the strike zone.
