A bunch of my favorite spots in currents are working rips and boulders...
Bass also act alot like trout do in streams... (Go find a nice trout stream and walk along the edges quietly... you'll see little trout hanging out behind the rocks... neet thing it is... and more fun to toss dry flies infront and wait for them to float up and slurp em down)
Hiding behind boulders in the current waiting for food to float by.
Another favorite is working heavy boulder beaches with poppers and rubber.
Never know what might come storming out from behind the shade of a boulder.
And yet again, big bass, IMO half the time, are freaking lazy. You damn near need to take wild guesses as to where they're hiding and literally cast ontop their heads to get them to do anything.
