Are the flatties really having a big impact on the bass? Some great bass rivers out in the NW part of the state are also great rivers for flatheads, but then again they are both native and have been interacting with each other forever. And one thing I find funny is smallies also aren't even native to eastern PA ;-)
springer1, from what I've read/heard and a little from experience flaheads are mainly a live bait(panfish, suckers, etc.) deal, but I know people occasionally catch them on cut bait and even artificials when fishing for bass and other stuff.
