HIya - I had a 38lb Agir wing with my twin 7s (when I used to dive them) and it worked fine - slightly narrower than the Halcyon wing which left less excess to wrap.
Having said that, we held the new Evolve wing against Daz's twin 7s on Friday and it looked like it would be a better fit. So you could think of this one - albeit you would have to import from the States as it is not available in the UK yet.
Both of these wings will do for twin 12s and several stages should your diving progress.
