I like DIR in principle.
Stream lining makes sense.
However I'm not a purist.
I have 6 D rings.
I don't wear Jet fins, they won't fit over my drysuit boots.
I have rubber fin straps. In 25 years I have always found the straps fail when you put them on.
I carry spairs, already threaded through buckles, quicker to install on site.
I wear a backplate and wing, I am a wreck diver.
I have a 2 inch quick disconnect on my left shoulder strap. I wear my light cannister on my right, clipped to my backplate, not my waist belt. I position the switch on the bottom so I can reach back under the cannister and activate it. I carry my light in my right hand, w/Goodman Handle.
I have an air integrated computer on my left side,on a retractor and analog console on my right (redundancy) clipped to my front waist D ring.
I use a 7 ft hose, laced around my neck,(during penitration dives) on the left post of my doubles, my octopus is on a necklace around my neck. My back up regulator is on the right post of my doubles manifold, the 2nd stage is in a yellow keeper, clipped to my right chest D ring.
My lift bag is stowed in a sleeve, clipped on my right, beside the cannister. My reel is clipped my right rear waist D ring when not in use.
As a wreck diver I must carry all my gas with me.
(If you disagree read "The Last Dive")
My deco bottle gets clipped to my left chest D ring and left rear waist D ring.
My Argon bottle is clipped to my backplate left side, I have a back up inflator hose on my primary regulator, under my left shoulder strap. (I'm Canadian, we dive all year round)
My back up mask goes in my right thigh pocket.
My cylume stick, tables and Jon line go in my right waist pocket(two compartments, zippered).
My left waist pocket is not accessible if I'm carrying a deco bottle, so in it goes, my spair car key.
I wear a flip slate on my left forearm.
My spair light is clipped to my waist belt with fastex type connector, and I also have a mini Q40 clipped to my mask.
I still wear my knife,on my right inside calf.
I've seen too many divers sheathing thier knives firmly into thier suits. I can reach my calf and I can see it when I return my knife to it's sheath.
For single tank non-deco dives, I drop the back-up reg and deco bottle.
I don't wear a crotch strap, never needed it, my buddy does however.
This configuration works for us.
