Good points...I also look at the chip stack sizes but you made me think about the one or even two guys with the large stacks??? That is now on my checklist for game selection! I have noticed on some tables in my search the "maniac" or loose/aggressive player or players. I've read and heard others say to stay away from those tables...or beware! I have had some success playing against these guys...and my approach has been more direct and not attempt any bluffing or slow playing.
