I leave my hand as relaxed as I can get it in about the same posistion as if I were plucking a sequence, i have the wrist even more loose than the hand, my thumb/the meaty part of the thumb is what makes the bulk of the snare drum sound of the strings on the frets. When I need to i can lean in on my thumb and push that snare sound or conversly lighten it up so that is becomes a mute sound where all the strings choke off without a percussive snare/slap sound. The thumb is contacting primarily the Bass strings and really it is mostly the E and A string that makes the snare sound, sometimes the D string as well. My curled finger tips and the meaty part of my thumb on the bass coming down all together are the full execution.
