Just in case it will help anyone else traveling to Maui soon, here's a brief report.
I went with Lahaina Divers to Molokai and was not disappointed, we saw 6 hammerheads together. In addition the reef at Molokai is well worth the trip itself......pristine!
I also went to Lanai with Lahaina Divers. We did Second Cathedral and Lighthouse. Both were great dives. I found Lahaina divers to be very professional and would consider them a tight run organization. I don't know who the owners are but it is obvious that customer satisfaction is stressed to employees. I plan to go back to Maui next spring/summer and will certainly dive with them again. We didn't get the cattle boat feeling at all.......everything from the shop to the boat and crew were top notch.
For our Molokini diving we went with B & B. I found them to be a very friendly and professional crew as well. When we return to Maui I will dive with them again too. My wife thought the boat was a little small and crowded but I was was fine with it....they utilize the space well. A rumor I heard when I was there is that they may be getting another boat. We'll see when we return.
We also did some shore dives with Shaka. Doug has good knowledge about local diving........I would say 5 Graves is a "must do" shore dive.
Hope it helps someone!
