Its all about timing really. So long as the really old guy who typically runs it isnt there, you can snap away.
As for technique, you just push and pull the sail until you start getting as high as you can. Once that is acheived, you continue doing so, but you push/pull it sooner (Id go roughly with 3/4 before full movement up/down and then finding the rythym there) so the carriage begins to peak before the move is finished. When done right, you will begin to feel more and more lag when youre at the lowest point. Keep doing that and you will eventuqlly get the car to slow enough in comparrison to the ride to make the cable go lax and cause that oh so delicious snap.
Also, a heads up for the rest who wonder in here in regards to snapping Flyers - Kings Dominions Flyers are snappable, and you wont get yelled at for it!
