I havnt taken any classes because they dont speak DIR in my area
I do dive with Dir divers and instructors ,,, and the food part seams to stick out the most
I have seen some pretty big and out of shape DIR divers
Now on the other side
I have dove with folks who will start talking bad about DIR without the subject even being brought up
(Mainly from PADI instructors)
I was even told by a Padi Instructor that my DIR-F book was the biggest joke he has ever read
I am not a borg diver
but my gear looks dir to most and I follow the points I believe to be sound
Just my two cents
feel free to flame ,,I can take it
Dive safe
