How necessary would you say Poker Tracker is for playing $2 NL on pstars? I know it would probably help, but at the same time I can't really drop 90 bucks right now without being sure its going to improve my game- (dl'd it a long time ago so free trial is up w/o me getting to use it).

Does PT make decisions in low stakes pretty much automatic based on things like fold to cbet and 3bet percent? Most people seem nitty as hell in 2NL from what I can tell.

Another novice question- do you think it's possible to clear the stars50 bonus at 5NL or are you thinking at least ten cent big blinds are necessary?

Thanks for helping out someone new to the online poker community.
