Also more generally, "8 ever 9 never" really only applies to situations where there is no other information. For instance, if you are playing in an 8-card heart fit after RHO has bid an unusual 2NT showing ten cards in the minors, you probably would not choose to finesse RHO for the queen of hearts, even if you could only finesse in one direction through RHO.
In a restricted choice situation, you have some additional information from the play of the cards, so "8 ever 9 never" doesn't apply any more.
