I would prefer o2 addition on the right (the old right rich addage).. Even with reverse flow you can still have o2 on the right WITHOUT having to send it into the inhale counter-lung.. Tracy's Shadow Pack has a right to left flow with o2 addition on the right and it does not go into the inhale lung..
Quite agreed.
Guys, you all ought to remember this: What was shown is a prototype. All of the little design details are easy to rearrange. I didn't even look at anything other than the head. *That's* where the design is. The rest are just plug and play stuff that can be changed at the drop of a hat from a design standpoint. Who tore the head down to the last part other than me? If you were not impressed, I'd be surprised.
