Ill try to explain it the way i do it. . .
The Claw (aka the Casey Claw)
grab the stick in a fist in your right hand, almost dead center. Next loosen your wrist and strike the drum in one motion as if your shaking your hand after writing a long time, now make sure that your stick is hitting tip to butt. Now diddle your left hand. thats it! (written i think it should look like this . . B T L L B T L L) "Butt tip left left"
Estimated time of learning approximately 25 minutes
Estimated time of mastery . . . depends on the player
Hulka Helecopter (aka hulka or helecopter)
Do the claw with both sticks, just dont diddle

heres a video with Xaeroshin demonstrating it, its the last visual, enjoy!
