Here's couple things that work for me:

If you have almost 3D throws on the rudder, learn not to push the rudder stick all the way during the snap.

Unload the elevator.

Modulate the elevator and/or rudder input DURING the snap to line up your exit.

Don't be afraid of opposite elevator input on exit of certain snaps. 1 1/4 on vertical upline comes to mind.

Slight opposite rudder just before you exit is very effective for aligning the flightpath for full snaps ( 1 or 2 continuous)

Some additional same direction rudder input (you're not flying full rudder during the snap by now, are you ?) just before exit of 1 1/2 snaps aligns you as well.
