Even though I prefer DIN, I finally tossed in the towel and went back to yoke.
The problem I had was that I could never find DIN tanks when I travel. So I always had to bring my yoke adapter, which meant one more piece of gear to carry, more weight and a bigger regulator. That didn't make sense because I purposefully set up my gear to keep weight, regs and hoses to a minimum by using an Atomic T2 reg, an Atomic SS1 titanium safe second/inflator and a Suunto air-integrated computer.
As far as performance, though, there was no difference between using my DIN and using it with my yoke adaptor.
And there is something to be said for flexibility. It just wasn't worth it for me.
