Hay Scott,
Great name by the way.
I switched to steel HP tanks a few years ago and had to convert all my regs to DIN. Most of the DIN adapters that I've seen are easy to remove and install which makes switching back to a yoke easy. Just carry the proper tools in a dry box along with the yoke you removed from the reg and if you ever need to make the switch you can do it on the spot.
If you don't want to be switching adapters all the time then you can buy a DIN to Yoke adapter that the DIN first stage screws into and you can then use the reg on a standard valve.
Take a look at the pictures on this ebay auction if you've never seen one of these before and you'll get an idea of what I'm talking about.
