OK, I admit it, the rEvo design does have one minor flaw. No rebreather is perfect, not even Paul's . The stock crotch strap slit provided in the lower back support is too narrow for a standard 2" webbing. So I've been diving the unit without a crotch strap until now. To be honest, coming from a technical OC world, I feel naked without one. The 1" strap is even worse, it feels (and looks) like a thong. Not being in the habit of wearing thongs on regular basis, I always wanted to get the 2" crotch strap installed. And today, I finally did it.

For the scooter and butt D-rings, I used fixed 90° low profile. I definitely like it in the back for easy clipping of reels and spools. The front one through, I may change to a standard non-fixed floppy ring after I test it in the water tomorrow.
