Hi.
I used to dive twin 7s and an Agir 38 lb wing was pretty good with them.
Please note the used to bit though - twins 7s are not really any good for gas management so you can't use them for Tech 1. If you can mange 12s at all then do it. The Agir will do for 12s too though if you have to change up later on.
I swore that I would not be able to manage a bigger set - as Kerslake gleefully reminded me when I borrowed his twin 18s last week
