Two things on the Youtube wont work very well for compounds. One He has very little tension on the bow string otherwise he would be able to get it to flip around like that. Also since it is a recurve , traditional bow he isnt going to have to worry about a peep so there are probably a minimal amount of twists in the string. You put a string under 2 -300 lbs of tension while you are serving it and you wont be able to move the string to flip it around like that , guaranteed.
