I’m a DM Candidate with Discovery and would certainly recommend them. They rarely go north of the Cape Lookout shoals though and not all the way to Hatteras. Same with Olympus. Under Pressure in Hatteras has a good reputation around here but I’ve never been diving with them. Should your trip take you to the Morehead City, Beaufort area let me know as I dive this area every weekend. Hope this helps.- Danny
