Give me a day or so.

I had to replace the enviro caps on the 1st stages so I could switch directly from my singles to doubles and have hoses routed cleanly. Personally, I didn't really trust the sealed caps to begin with, so making the change wasn't a big deal for me.

Good pics.Thanks!!
I put 200 bar valves on 200 bar tanks, and 300 bar valves on 300 bar tanks. AND... I dive an H configuration all of the time.
1) there is absolutely no strength advantage to the 300 bar DIN fitting. They were not made deeper to handle the extra pressure, but to eliminate 200 bar regulators from being used on 300 bar valves. No, there are no 200 bar regulators currently being made. The deeper DIN is a solution to a problem that in reality does not exist.
2) the yoke insert makes it easier to share a tank with a bud if needed... or if you want to try a different reg that is set up for yoke... OR... (add your own contingency here, there are a million of them). Flexibility is always a plus.
3) The best advantage of the DIN system is that it eliminates an entanglement hazzard. Many yokes are rated to 3500, so there is no safety issue there... no more than say pushing a 2250 psi tank to 3500+psi. Think about it.

Actually, there are some regulators that have a 200 bar din adapter... Mares, OMS regs, and others...
And, 300 bar DIN is capable of handling the 300 bar cylinders in Europe. 4350 is a lot of pressure.
Also, the main advantage of a DIN is the lower occurrence of oring extrusion on a DIN over a yoke (basically, it doesnt happen on DIN setups).

O-ring extrusion does happen on a DIN... and it's happened to me twice on a 300 Bar valve too.
No manufacturer that I know of currently produces a sport DIN regulator. I think that Scuba Pro was actually the only one to limit their regs in that manner and I believe they stopped that at least 5 years ago. Of course, produce some model numbers so we can see differently and I will stand corrected. All 300 bar DIN regulators will fit a 200 bar din valve.
Now, you might be referring to the din to yoke converter that all reg manufacturers sell. Thats not what I am talking about here.
But the question was the benefits of a 300 bar DIN H-valve over a 200 bar DIN H-valve. There are none. Flexibility is the primary advantage of a 200 bar DIN H-valve over it's 300 bar cousin.

NetDoc, I originally started this post just to see what people are using. Dive RIte has discontinued the 300 bar H adapter and I just wanted to see if people were using more of the 200 bar or 300 bar.
Now, when I was talking about a 200 bar DIN adapter for a reg, thats exactly what I meant. I am a Divecon Instructor, a service technician, and a dive shop employee. I do know what I am talking about... I have it right in the back room. Its for a Mares regulator. I have an OMS reg here for a deco bottle that has a 200 bar din adapter on it. It does exist. There are no model numbers to give you. Anyways, this info is not that useful...
By Sport DIN, what do you mean? A 200 bar? If so, I just proved you wrong.

I never meant to suggest you did not know what you were talking about, but you asked for our input and you received mine. I only took exception to the myth about O-ring extrusion. It happens, and I am not the only one to have seen it.
Mares does seem to offer the short or "sport DIN" which was promoted by ScubaPro. ScubaPro now only offers the original DIN configuration. OMS claims that their valves only come in the original DIN configuration and always have. I did not take the time to check ALL of the other reg manufacturers to see what they offered.
In the not too distant past, reg manufacturers were worried about how the innards of their regs would react to higher pressures. In fact this was one of the arguments against going to them thar high pressure AL80s from the "safer" lp 72s (that and really bad buoyancy issues of the early AL tanks). So, when DIN first came out there were few reg manufacturers that were ready to let them be subjected to 300 bar. Not wishing to lose market share, SP adopted the "Sport DIN" concept which made it impossible to attach a 200 bar DIN reg to a 300 bar DIN tank. However, a 300 bar DIN valve will fit just fine on a 200 bar DIN valve.
BTW, you won't be the first person to "prove me wrong". I don't mind admitting when I am wrong, and was open to that reality in my post. As I said, no manufacturer that I know of, and that was true... I knew of none. Now, we now know that at least Mares still offers the sport DIN, though we are not sure why.
There is simply no structural, design or safety reason that you can not use a 300 bar DIN regulator in a 200 bar DIN valve. The converse is not true. You can buy a 300 or 200 bar DIN valve (H or otherwise) to fit 200 bar tanks. You cannot buy a 200 bar DIN valve that fits a 300 bar tank. Consequently, my Hp S120s have a 300 bar DIN valve and I have two AL80s with the 200 bar convertible DIN valves.
