I would just like to say kudos to TDI for recognizing the need for a class like this. I hope the standards will be such that one can be confident of a quality experience in taking this, but even if there are some variations, it is still a class that is very much needed. I recommend DIR-F repeatedly because, to my knowledge, it has been the only option for a non-technical diver to be introduced to a higher standard of skills and to such non-mainstream things as a long hose/bungied backup configuration, and non-silting kicks. But if TDI is going to offer the same curriculum, I can steer people in that direction as well.
