The Ballpark would be cool. The thing with Jerry World is it's not really outside, which depending how you look at it is either a blessing or a curse. Personally, I'm happy with playing in one for now, I doubt hosting one is really all it's cracked up to be.
I've never liked the idea of JerryWorld for a Stars game. I thought the whole novelty about all this was about playing outdoors more than playing in a big stadium. Even if the roof is open it won't feel like an outdoor game. Ballpark makes the most sense, smallest capacity and easier to make sure they sell out..and it's actually OUTDOORS. I'd personally like to see it at the Cotton Bowl but I think that's very unlikely.
