I have been pondering the exact same thing, I think I like the AAR wing, but did not want to look like an AAR clone... Go-Wing seems a bit tall for me, what does the Gull wing look like.
Then again, you still can not go wrong with no wing, either way looks great.
Sorry, to derail, but does the 'cuda need a wing for rear downforce at high speeds? Or does the front lifting at high speeds render this useless?
