For cleanest mortises, do you prefer the two-prong recip bit over spiral upcut? Do you always use side to side motion with gradual plunge, as shown in the video, or do you find it sometimes preferable (e.g., for deeper mortises) to make a series of full depth plunges with hole edges just touching, and then clean up with quicker side to side passes than would have been reasonable before the plunges removed the bulk of the waste? Thanks.
