I am replacing some old 5/4X8" pine deck boards which are nailed to
2X6's. I'd like your favorite methods for doing this, as the time
consumed will be largely the removal of the old boards, not the
replacement of the new ones.

Cut them with a circular saw parallel to the joists (about 2" away).
You should then be able to pull them up easily by hand. I do this
between every joist, it is a few minutes of cutting that makes pulling
them up much easier/quicker.
