Yes, some DIR divers do have an ego, but then again so do a lot of the 'techies' we get in the UK, you know the kind, black drysuit shaved head.
DIR is a good system, but a little too holistic in its approach for me. The team system is a good idea, when the vis is OK, but when you can't see your fins, let alone the team, then I'm ot sure how much help it would be.
I know some people would say "Well you shouldn't dive if its that bad" but that means I might only be able to dive 4 months of the year from the South Coast.
*Long hose and backup placement - excellent idea
*Wings and backplate - perfect, modular and upgradeable
*One piece harness - bit tricky for use on a RIB (Rigid inflatable boat) where you take your kit off in the water first
*Lots of helium - good idea (and a funny voice on the boat always makes people laugh), but a little narcosis is not such a bad thing, I find it helps to focus one's attention
I hope this whole thread doesn't kick off into a big slanging match "I'm a better diver than you because I dive DIR" type thing.
I think picking the name Doing It Right might have been the catalyst that peeved a few people off, ie. suddenly inferring they had been Doing It Wrong all their lives.
At the end of the day, when assissting students, I wear normal scuba gear, but I have my wing, backplate, 7ft hose (and dreaded one piece webbing) for when I am out on the boats with me mates.
So whether or not we should all be Doing It Right, or not, I prefer to JDI (Just Do It - bet Nike wants me for copyright infringement on that one!!!)
