Tip for shooting in the wind: If you've got a level on your sight, tip the top limb into the wind until the bubble slips to the other side of the level. It makes it easier to hold and puts a bit of pressure on one side of the arrow to drive it upwind a touch.
Hmmm... now that I think of it, I know this works with prong rests but I wonder if it works as well with drop aways?
