Bankroll Decimated, what to do?

[Baked67]

So, I play the 10+1's at Pokerroom parttime yadda yadda yadda. I had a rough go of it a week ago. Varience IS a bitch. I usually play with a roll of 300, but after a downswing of 16 tournaments my bankroll is serisously hurting around 140-160 bucks. I moved down to the fives to try and weather the storm and things have started turning around for me a bit. But when should I move back up? What do u guys do? Should I wait till I have 30 buy ins again to try the tens or should I try and take a stab at them a little sooner...
