Jeff,
I used to think biting off as much as the cross bunker as possible, to get into the slot was the best way to play the hole until I examined the schematic in the basement which revealed the hole to be straighter than I had thought.
Going up the slot, may give one a shorter shot into the green especially if the pin is on the far right plateau, but the angle is very uncomforable for almost every other pin position, especially when the pin is further left.
From watching the McBrides play the hole, I've found that the best route for me, no matter where the pin is, is to hit it just slightly to the right of the center bunker, close to the rough, leaving me an uphill lie. This usually leaves me with a more lofted club into the green and no fears of inadequate trajectory.
HOWEVER, reaching the green in regulation is just part of playing the hole. Putting on that green can be a trying experience with the ridges, plateus and bowls.
Hitting on the upslope in the fairway near the center bunker usually allows one to come into the green with a more lofted, shot and club, making it easier to properly position your ball, depending upon where the pin is located. If the pin is far, front left, missing the green left and short isn't the worse position to be in.
The hole requests, but doesn't demand four perfect shots.
But, despite BV's claim, the hole must be played aerially.
I don't envy first timers, but the hole sure does grow on you.
