I started out with used yoke regs that I had serviced....breathing was still like sucking an egg through a straw.
So I bought new regs and went with DIN HOG's. I loved my HOG's, the DIN to yoke adapter....not so much. In fact, I disliked it enough that I finally bought an EDGE first stage instead of messing with the adapter all the time. I am a travel rec diver and I think I was able to use my HOG's without the adapter once or twice in about 250 dives.
Sooooo I have been from YOKE to DIN and back again
I would never advise anyone to start out DIN.
But then, that's just me.
