"The chief advantage of this is that the "correct" response can be used in the rollout rather than the GNU 2 ply evaluation used in the basic rollout which is not always correct."

There is a problem with that approach. Let's say you want an equity of a position with say 43 rolled. You rollout the top candidates and report as the equity the equity of the rollout winner. This gives a biased estimate of the equity of the position.
