I've noticed that as well. It's too bad as it gives the rest of the DIR community a bad rap.
I asked, while learning some DIR stuff, that if I showed up at a place to dive, as a single diver, would I be able to hookup with some DIR divers to practice with. The answer I got was " ahhh you could.....but I doubt you'd find anyone there wiilling to dive with you".
What kind of crap is that? Do you have to take fundies before anyone will dive with you, so can you practice, so that you can be better prepared for fundies? I've heard half the divers in fundies shouldn't even be there, skill wise. I'm sorry I was just put off by that. Like all of a sudden, all of my diving experience and skills to date meant nothing. BS. I was also a bit put off by the video reviews. Every now and then a camera found it's way pointing to some rather large guts from another class in the pool. It seemed funny but then it got a little un-professional in my opinion. I realize DIR is a holistic system but let's not make fun of others to prove a point. All the while taking money from overweight divers. Coach them. Give them advise but act accordingly. It's this crap that hurts DIR.
