Waiting for the water to warm before the first OW dive, I have some concerns about equipment to buy. Mainly, I am thinking about the secondary air.
This is your first open water dive? you profile says "not certified yet".
so I'll assume you don't have any open water dives under your belt.
For that reason, you don't need to add "task loading" of having a pony slung and having to deal with it. They won't be teaching that in your OW class. They will be teaching "how to dive with the Octo attached to your first stage".
So, don't over confuse yourself, overload yourself, etc. Just dive with the Octo like they are teaching in the class. You won't be diving in any depths that you can't save reach the surface or not reach your buddy in the event of an emergency.
simple as that.
After you get some dives under your belt and some experience and want to take some more classes, you can worry about slinging a pony then.
