Barbeau is also a bit more choosy about the indies she does. Comes with being John Carpenter's wife. And she's pricier.
Blair isn't really a consideration anymore.
Also, we need to be really careful about this thread. The last thing I need is some wanker going off and saying "I read on some forum that Felissa Rose, Adrienne Barbeau, and Linda Blair are doing this weird feminist horror indy!" and then I'm known as the sleazeball who lies about who's in his film.
