Yes. My LDS switched from PADI to SSI. Not only for the above reasons, the shop no longer has to deal with PADI’s timetable. With PADI, they have the Regional Course Directors (or whatever the official name is) that have to come around and a certify people to become Instructors. If your timetable doesn’t meet there, too bad, so sad, you have to wait until they can work you in. Under SSI, a local instructor can now be certified to be an "Instructor’s Instructor" and can now take students from O/W all the way up to Instructor. You can also stay with Padi and offer and/or certifications.
Financially, it might be a good move for you Greg.
