The DIN connections however are more for high pressure steel tanks. These require the more secure DIN valves. Low pressure steel tanks can accomodate yoke valves and aluminum rental tanks are just about exclusively yoke.
If you are planning on purchasing a high pressure steel tank in the future for local diving then it would be wise to go DIN. If you plan on diving mostly on vacation the pick the connection you will most likely encounter.
This is totally wrong. Both Yoke and 230bar DIN are more than good enough for handling 3442psi - HP tank. Unless you plan to use tank with higher pressure. DIN is more secured because of the way the connection is made, nothing to do with operating pressure, at least in US.
To OP, if you decided to go with DIN reg with yoke adaptor, try to borrow or rent such a setup to see if 1st stage sticking out is an issue for you. It depends on your rig setup and your physique. In my case, it bothered me enough that I actually went from DIN to Yoke. I will buy DIN 1st reg (2 of them) again when I move to double. The cost of an extra DIN 1st stage, especially if you buy used, is so smaller compare to a tech double setup. I think everyone should agree on this.
