Who disagrees with DIR and why?

[LKunze]

Here's a thread for non-DIR divers to tell what they do not like or disagree with about the DIR dive system. I am not starting this thread in hopes for it to be a flame war. Keep in mind, I am not a certified DIR diver myself but "lean" that way. I'll probably take the DIR-F class next year if I have the cash...yep, I know excuses, excuses. : Anyway, I've read a lot on DIR on internet forums and websites, have listened to all of the DIR audio lectures I could find, read the DIR fundamentals book, etc. I am pretty familiar with the reasons "why" things are done the way they do them in the DIR system. I guess I am curious as to "why" people don't agree with DIR practices. I'd like to hear specifics on this, not generalizations like "I don't like DIR because some a**clown on the internet said I was a stroke" But rather things with some substance like:

I do not like the long hose and bungeed backup regulator configuration because ___________

I do not like a backplate/wing because_____________

I do not wear my instruments (bottom timer/computer/compass) on my wrists because___________

I do not agree with the way DIR diving handles their gas management and labeling of gas mixes etc. because _________

I do not like the DIR fitness standards because___________

**Feel free to add anything else to the discussion. Just trying to get something going here because I know several divers locally dive a DIR-esque way but do not fully agree with the DIR system. Some people who are not DIR but are curious about it may learn some things from the discussion as well. It will also give a chance for someone who subscribes to DIR to offer some counter discussion to those who disagree with certain things in the DIR practice... (keeping it civil and constructive of course. )
