I don't have any good advice other than suck it up and move down when the bankroll is really under threat (doesn't sound like it is at the moment). 160 BBs is not a huge downswing at 6-max (nor necessarily a really huge downswing at full-ring).
Although you may not recognize me as a solid player, I'm guessing you recognize Entity as a pretty good player. Look at his graph in
this thread for some perspective.
