Shape the throw. It will need a definite outside-in curve in order to slow down and hold up for the receiver. Just be wary of showing the underside of the disc to the wind; when throwing into the wind, deliberately angling the disc like this makes the wind act as a brake, slowing the disc down. When throwing downwind, you’ll want to aim high to slow the disc down.
Cut straight. If you head for the back cone too early, you’ll reduce the amount of width that the thrower has to work with. Instead, cut directly deep until the disc is thrown, then go fetch! By cutting directly downfield, you’ll also enable the thrower to throw the more conventional “straight” throw as well as cross-field… the marker can’t stop both.
