Rarely if ever are players excited about bunker shots. Best advice I can give is try some different options. See what club in your bag you feel most comfortable with. Move the ball position around in your stance and see what produces the best results. Some players benefit from a more square face then the traditional open it up as much as possible method. Sometimes just getting the ball out is the best play. After a small amount of practice and using some different equipment often times bunker play will improve drastically.

When hitting out of a greenside bunker, how would your technique change for longer vs. shorter shots? More swing? Different clubs?
