Bankroll Question playing deep stacked

[McRoNiX]

I play 100 and 200nl on absolute where you can sit with 200 bbs. I always do this as I believe it gives me an advantage and maximizes my profits.
Was just wondering if I should adjust my bankroll management. I only used to sit with 100 bbs and made sure my bankroll was always 25 buyins (eg, for 100NL sat with $100 and had a min bankroll of $2500). Should I now try to have 25 buyins when I sit with 200 bbs or is the same bankroll ok?
