Hi Fred,
I'm pretty sure I replied to this thread but my post seems not to have made it somehow.
I think I basically said that for unlimited shorediving Dauin is great. There's not much shorediving in Malapascua, although a quick 2 minute boat ride will get you on some of the best macro around.
Depending on your budget try Atmosphere or Liquid, although like Jim says, sometime the current might be an obstacle.
If you have other questions on Malapascua, then feel free to ask. The Dona Marilyn is a great wreck by anyones standards and the Tapilon is fun if yo're into history and some artifacts, there's a bunch of Japanese stuff there.
Good luck and enjoy.
Matt.
