Remember that a scarecrow is just a front roll to revert so you'll need a progressive toeside edge with little more weight on your front foot and a little more pull from your rear hand. As you leave the wake, look at the opposite shore and make yourself as tall as possible to maximize your lift. Notice how Shannon uses his head and shoulders to lead his rotation. Now, do a true front flip at the peak of your rotation, pull with your rear hand and look in the direction of the boat for orientation. It may be helpful to let go with your lead hand upon landing to keep the rope at your hips.
