Although I always enjoy learning new moves there is little interest in learning the same move both ways as the tack is purely practical so at the end of the day I end up always doing the one i prefer (or do best) which is the "round the mast type" for ex windsurfers .
I remember learning the toe side tack few months ago (switch the feet before starting the tack) which can only be done as a duck tack (loved this move on a windsurfer) but use it very rarely these days
