One of the nice things about the SSI course structure is that you can take the specialties (like Stress & Rescue) in any order you want to, at any time. Also, with SSI the "AOW" and "Master" diver ratings are very flexible in the course content required, consisting of four or five specialties, and 24 or 50 logged dives respectively. For Master one of the five specialties must be Stress & Rescue. As an extreme example, one with exceptionally good diving skills might opt to "just stay in the classroom" following open water training, and take four specialties. If the four were taught as a package, they could be offered with six rather than the normal eight dives, so with as few as a dozen logged dives you could have completed the specialty requirements for AOW. However, at this point the card you'd get would be "Level 2 Specialty Diver" - the AOW card wouldn't be issued until you'd completed 24 logged dives. If you did another specialty, and one of the five was Stress & Rescue, then at 50 dives you'd earn your "Master Diver" card.
There is tremendous "political" pressure on SSI to abandon the experience dive requirements in favor of a "course only" requirement like other agencies - but many of us (me too) feel that the experience + course requirements for the SSI card brings more meaning to the rating and should be maintained.
I also like the ability within the SSI system to tailor your own course to make it more useful for the kind of diving you intend to do. For example, if your passion is photography, you might choose Underwater Photography, Fish ID, and EAN as three of your four AOW specialties rather than the more traditional courses.
Bottom line - I like the SSI system and hope they don't cave to politics.
