I can get into the wrist mount ;D, get into the next bit ;D and double on ;D, but how do you pop it and cross your hands? ???
When you pop, pull both hands apart quick, and cross your freehand over your throwhand and land on that single string.
When you pop it up make sure your non throw hand goes OVER your throw hand and cross it after you pop, if you cross to soon it wont work.
