shot shaping is bad enough in real life. alingment,stance, swing path, ball position, wind direction and speed then commit to the shot.
the ball goes further with a draw than with a fade so WGT you need to take that into account.
at the moment i miss the centre line left or right to hold the ball in to the wind or bring it back on it. i very rarely hit the centre line or move the marker away from the pin to set the line. the same with the putting. shot shapeing i would see as a aid to get out of trouble or miss trees etc rather than a must have part of the game.
good luck in whatever you come up with WGT people will adapt to whatever the final system is.
