hahaz, qwerky, ya juz have to practise, watch DVDs and learn from trad players.
i'm sure many trad player will agree with me that trad is not something u learn on your own. ya have to be more careful with it cos proper technique is very important when it comes to traditional.
for me, i play trad at first cos it looks cool. but later i found out about the amazing things ya can do with trad. for example, it is easier for trad players to play a rim-shot, its easier for trad drummers to play louder juz by lifting up your hands(unlike matched, ya need to swing the stick upwards more).
but most importantly, no one grip is better then the other. each has its own art and style.
