Who disagrees with DIR and why?

[ghosch]

All the wholistic BS aside, what I dislike about DIR is that there is one right way to do it, and that's it. There are no options. Changes only take place when they are passed down from the hand of the mystical dive gods. That thinking process simply ignores reality, hence one of the common euphemisms for DIR.

I think the second or third chapter of the IANTD Encyclopedia of Technical Diving is on gear configuration (which I know is only a segment of DIR, but is what we focus on most here) at some point in the chapter (I don't have it here in front of me) there is a list of key points to consider in configuring gear. One of those is "Be open-minded!" In my opinion being open minded means acknowledging all the possible solutions and selecting the one that makes the most sense for the situation.

Arguing about long hose versus short, or donating the primary versus secondary is great stuff, as there is a legitimate exchange of ideas taking place. The argument "if you just practiced it my way, you'd understand" goes both ways. I could say the same about rebreathers vs. OC
