Hey Tim... sorry I missed you while I was on Maui -- I was in the water absolutely every day, but left having finished my MSD!
I'm planning on coming back soon (probably July) for an extended period of time... and can wholeheartedly and authoritatively say that the shore dives were the HIGHLIGHT of my trip.
Molokini is great... but Uniroyal Reef (part of the same artificial reef as the St. Anthony) is AMAZING (this was a "shore" dive for me, albeit on a scooter)! Lanai is cool, but the just-about-guaranteed turtle sightings at Ulua is INCREDIBLE.
If you're looking for a dive shop in South Maui (as opposed to the ScubaBus that Doug drives), check out Maui Dreams Dive Co... definitely a good group of people for both instruction and guided dives. They even have scOOTers that you can go out on... and if you haven't done a scooter dive... well, let's just say you have to try it!
Oh, and Maui Dreams also has a buddy book, if you're just looking for someone to dive with you might be able to hook up with someone that way.
Since this last trip, my previously-unwavering recommendation of Ed Robinson's operation has been diminished... I haven't gone out with anyone else, but I think I'll be trying B&B and Mike Severns before signing up with ERDA again. I can share more in a PM, but it doesn't need to be aired here.
You didn't mention when your trip to Maui is... send me a PM if it's in July (or later) and I'll go diving with you, too.
Cheers,
-kb
