Poly DPM and floating floor every time. Timber floors move about in varying temperatures you can see that by looking at any floorboards in a room. Gaps appear and dissapear all the time. If your floor is floating it will have the freedom to expand and contract a little and because of the expansion joints around the edges, should not be seen to do so. If the floor is stuck down and it moves, it becomes unstuck and stays unstuck until you take it up again. This can lead to a very "bouncy and noisy" floor.
