yeah, the stick swirl is just practise. you can throw it up in the air too, catch it and play. its all just practise.

to get a quicker snare response, praaaactise heaps and make sure your wrist are loose, if you try to hit the snare as fast as possible with a lot of tension on your arms, it won't work (plus it'll be out of beat) and ofcourse two sticks go faster then one.
