Aloha Steve, Mahalo for the warm welcome. Yes we do have bones in hawaii some of the largest in the world, don't get me wrong they're not easy to catch, you really need someone with alot of knowledge of tides, areas and accessibility to the many flats on the Island of Oahu, Hawaii. When you do travel to hawaii I will be more than happy to guide & show you our fisheries.
As far as flys are concern most guides have their own "go to" patterns but generally any crazy charlie in neutral colors work well. The bones are not particularly too finicky its more of presentation.
