Bankroll Question

[Reel Deal]

Do most of you keep your roll on the various poker sites you play at or do you keep just a % of it at the various sites and then keep a reserve at somewhere like Neteller?

I've usually kept most of my roll on Party and Stars then a little at places like Full Tilt, Bodog and UB just to play the occasional tourney there, and only use Neteller to transfer funds. But I'm thinking it might be smarter to keep a good chunk at Neteller and smaller amounts at Stars and Party.

Thoughts?
