Are you asking who I'd pick, or who I think the team will pick?
The story on the Flames website with Hartley saying they polled the players, management, and owners and had a virtually unanimous decision pretty much confirms it will be Gio (

As for who I'd pick, I would also go with Gio, but Glencross would be a close second choice.
I'd go with Gio for the C; Glencross and Cammalleri with the A's, and maybe add Stempniak and Stajan with A's as well rotating between the four of them. I'd also give consideration to Brodie and Galiardi for A's.
