Catherine, a large shop here is a Halcyon dealer, bring in the big name GUE instructors, all that. They also sell alot of Dive Rite Transpacs with rec wings, along with jacket style BCs. One of the owners is VERY DIR, to the point he is working on becoming a GUE instructor. I have seen him dive completely recreational dive sites still in his doubles and 18w HID. However he is also about to become an instructor for Inspiration rebreathers. He personally believes in DIR, dives for himself DIR, tries to further DIR, but still has to make money and offer what the customers want.
In a recent PM I mentioned I was just on your beautiful island and got to go dive, compared to southern california diving, Hawaii was just too easy. I told my wife it wasn't real diving, it was vacation diving. Ill admit I went below 100 feet on an alumum 80 filled with nitrox 21... however with the type of diving I was doing there, I saw no need for my doubles, drysuit, helium, (well I did take my 18w HID...)
I know of people that on recreational dives will only dive DIR gear, but they work sometimes underwater for filmwork. I was surprised that they prefer jacket style bcs when working because it keeps them in a vertical position making it easier to work/watch whats going on. So basically there is a time and place for everything, DIR does have a lot of good points, but it is not the only way to do all dives. Obviously we do not know each other, but you seem like a good person from what I have read of your posts, can you honestly say that you are as good of a person ALL the time as you would like to be? Everyone "slips"
next time I go to Hawaii, I am going to talk with you and find out what shop will take me out and not make me follow some DM who wont stop talking...including under water!
