You could always go the route I did ... have a chunk of steel take out your dominate arm and force you to play one handed for a while. It hurt, but man is it ever effective. Strong left!

start doing everything left handed, Not kidding, brush your teeth, comb your hair etc, also take a tennis ball and bounce it off a wall left handed, and start playing your hihat left handed or open handed!

I remember that broken steel spring story, you should have had a helmet on :)

Thanks, I'll try that !Excited

You'll feel like a fish out of water at first, be patient take it slowly, and you'll be surprised how fast you'll progress! pay attention to your stroke technique so as not to pickup any bad habits.

I'm not sure if the pro drummers would say this is a god idea but you might play open handed for a while.

I started out playing open handed and my teacher made me change to cross hand.

Even though I have only been playing a few years, I have become quite adapt at changing my rhythm hand from left to right. In fact, it's not unusual for me to switch in the middle of a song. Especially a long jam.

I start out playing the snare with my right and the hi-hat with my left (which is typical for me) but when I play my ride cymbal (which is on my right) I often switch to playing my snare with my left hand and the ride cymbal with my right. Even for a novice player I seldom miss a beat in between.

My teacher really freaked over this at first but eventually realized it was really making me a much more versatile drummer.

Like I said, most pros probably wouldn't recommend you do this but it seems to be working out for me.
