I think the first time one plays that hole the centerline fairway bunker that cannot be seen from the tee can be considered unfair. Not everyone desires, or can afford, to take a caddy that can alert one to that possibility, and even then getting a feel for the shot required NOT to get in that unseen bunker is really tough the first time one is playing BT.
After that, though, now knowing the unseen is there, I think it becomes a great feature that is no longer unfair, and must be dealt with. The speed slot on that hole is really between that unseen bunker and the huge waste area right, and that speed slot is so incredibly narrow as to make it a lucky crap shoot, really.
The true "speed slot" on that hole is one that allows the shorter player to take a modest club and lay one down the hill short left in the fairway for a fairly flat lie, even though one might then be using the same club, or close to it, off the tee and on the approach.
