bankroll managment/ new to 2+2

[kimos123]

Hi,
im new to 2+2 forum, i signed up becouse i feel that 2+2 forum will help me building my bankroll and becoming a better player.

i made my first deposit to pokerstars end of feb 2007, my deposit was $25, and now i am up to $116 playing cash games 0.02/0.05 0.05/0.10 and sometimes 0.10/0.25 and also SnG $5+0.5 and a few times $10+1.

i dont play everyday i play like 7 hrs a week sometimes less.

i would like to know when can i constantly play the 0.10/0.25 game becouse the buy-in there is about 20% of my bankroll and i dont think its a good idea to do that.

and also what is the best level to play at currently with my $116?

and if its good idea to play multitable tournements with more thrn 1000 players? i played 2 times and i finished both times in the money but didnt win alot only doubling my buy-in

thanks for the advice
regards,
kimos
