I got my hands on an Air Stag from the MP last week and have been surprised to see how overstable it is. I feel crazy saying this, but it's more OS than any other Stag I've thrown, even 173 VIPs. Makes me wonder if Westside is unhappy with how it molds up in Air VIP and that's why they aren't marketing them, at least in the States.
I'm going to spend some more time with it to make sure it isn't just finickier than other Stags, but I've gotten what I know to be a lot of clean releases with this thing and regardless, it fades out earlier than my other Stags. Weird.
