I currently play $200NL at a pokerroom skin and am about to move up to $400NL. I do not use poker tracking software. I play between 2 and 4 tables at a time. I play 5 handed cash game.

Do I need to use software such as PokerTracker or PokerOffice to make it big in online poker or are there players out there that have done it without the software.

Now that I'm going to start playing $400NL is it essential to use PT or PO?

Thanks for all replies.
