So I moved up to 25NL just a few weeks ago and beat it for 4.8 ptbb over 18k hands. During this time i got my roll to 1k (yeahhhh four digitz )

I took a shot at 50NL and immediately ran KK into AA for a full buyin and then continued to lose half a buyin on a questionable AK hand (http://www.flopturnriver.com/phpBB2/...it-t84100.html)

My roll is now 930ish. When should I move back down to 25NL? I'm thinking around 750 would be a good time but I'd like some input from others before I have my contingency plan set in stone
