is that not what fundies was designed for? People wanting to make the transition into GUE? Were there other motivations for TDI to introduce the course? sure, but the course is targeted at the people looking to transition into a different style of diving than the one they likely learned in OW.
Jay's comment sums it up, AOW will not teach you anything significant over OW if you stay with the same instructor, it isn't designed to, but if you need it for other courses in the future or to get on a boat, then you need it. If you are planning on technical training in the future of any kind, then I still recommend not taking it and going straight to intro to tech. AOW is not a requirement for this course, from any agency except for PADI. ItT will give you all of the skills and much more that most AOW courses will give you, and saves you time and money by not having to put another dollar in....
