If you want to be DIR, use the non-fixed D-rings. They clearly work fine, even with dry gloves, as many, many folks have demonstrated. It just takes practice.
However, if you want to used welded D-rings, then use them. Just know going in that they're non-DIR. If you plan on going down the GUE or UTD training path, you'll want to learn to use the non-fixed variety.
Personally, I use the exact welded d-ring you reference on my left hip and the angled welded d-rings on my shoulders. I also put two on each shoulder. However, my training is through TDI. I respect the DIR philosophy and its adherents a great deal and much of my diving is influenced significantly by the DIR system. However, my rig is not 100% DIR. I know that and I'm fine with that. If I had decided to go down the GUE/UTD training path, I would have stuck with the non-fixed variety.
It's a decision you have to make based upon your diving and the training path you'll be pursuing.
