Routing is another thing to think about...
I don't specifically remember with the 200 because people I dive with use 200, 100 and 50, but sometimes when I am rigging up Apeks regs on doubles, on the right post the 1/2 inch port for the primary does not line up where I would like so I use a 3/8 port for primary, so in this case, I need the adaptor to help plug the 1/2 inch hole, to size it down to 3/8 if I will use it for the inflator.
Sometimes, the 1/2 lines up nicely on the left post for drysuit, or Octo, then I need the adapter to 3/8 to use for this purpose.
Anyway, if I knew the routing on my rig allowed the use of the 1/2 inch, why not. But then again, if you are diving with folks that do not use Apeks regs, that means you have an incompatability between you and your partner, making sharing hoses potentially more difficult, or impossible if they do not have Apeks, and you lack an adapter.
I use 3/8 hoses so they can be shared by the widest audience in case of unforseen emergency...and carry a few extra adapters....
