i plây drums since 6 years or so, never had much problems with my wrists,
i play with light jazz sticks, don't like the fat rocksticks
i play very souple, and yes, sometimes my sticks just fly out of my hands,
my drumteacher told me some techniques one day, had to practice alot cause it DID change my style of playing
the difficult thing is; i just can't explain in text how to do it,
just loose and souple(is that an english word?) don't hold them like if they were the last sticks on earth,
and yes, i can even hit my drumkit REAL hard without hurting myself,
i don't always use my wrists, lots of the time i just hold the sticks
between my THUMB and my index finger, NOTHING else,
the three other fingers just go "up and down", they make the stick move,
when the stick hits the batter, it goes up automaticly,
this way you can play even without moving your arm or wrist,
yeah, even without moving your index finger and thumb,
just by moving those three other fingers (fast or slow;;;
this is just one of the things i do, maybe i'm fucking up my own wrists,
don't know, just don't have much pain right now so i think i'm doing fine
lets call this the finger technique
just my two cents,
cheers,
