After years of diving Molokini, guiding Maui divers, listening to other Maui guides and hearing feedback from visitors who dove Molokini I am of the opinion the Backside of Molokini ranks as the 5th, 6th & 7th best dives at Molokini (depending on where you drop and which way the current is).
I have to agree with this. After all the hype of this dive, I was really puzzled when we did it, and I kept wondering where the fabulousness was . . . I was hoping for pelagics, but we saw none that day. I think it's probably an exciting dive, if you have never done a wall that fell off deeper than you can see, though.
As far as I can tell, the biggest determining factor on doing the back wall isn't who the divers are on the boat, but what the weather and water conditions are -- a lot of days, the current or the swells are wrong for doing that dive, so you can't ever really count on it.
