no tools, just playing

[mle]

i play two or three games at a time (nl 5-10, nl 10-20) and don't use poker tracker.

i'm more old school and don't want to analize stats...i feel like by watching and note taking i can get the info i need about the other players..

is PT necessary if you only play two or three games at a time? is it so great that i'm stupid not to try and use it??
