aproach the knuckle with 5x the amount of speed necisary, pick a spot on the ground on the knoll, and pretened you "dropped something" on the knuckle. Let your legs drop out from under you, and reach down/back and if done correctly, your legs should come around at either 3 or 5 depending on the size of the drop. Also consider the fact that if your going for a Handrag 3, you don't need to spin whatsoever. This might sound crazy, but if you think about it, your already almost at 180 before you get off the snow, and the extra 1 will come naturally.
