First: The Spit 5's performance is now (again?) its more historical self. I know, I know, there really were super spit 5s like we've had for the past year or two, but the current version is what I think of when I think of Spit 5s. The result has been that you can actually have good fights between Spit 5s and Axis planes, very fun. I liked those fights so much that I might overcome my anti-spit bias enough to include Spit 5s in some of my setups.
Second: While the Spit 8 and Spit 9 are still plainly superior to almost any other plane that attempts to fight them, they CAN be dealt with (not that I could, mind you, but I saw other people who did). Much of the fun I had in this setup was watching the Axis devise tactics to deal with the Spits. Spits 8 and 9 are still girlie planes, IMHO, but they aren't super planes.
I know there's been opposition to having the Allies restricted to Spits, but this forced people to fly spits (thereby reducing problems of conscience) and forced the Axis players to devise ways to deal with them. If you only flew for one night, the experience ws probably ugly, but if you flew more than that, I think it was interesting, educational, and actually fun.
It was certainly a setup that would make you conquer any fear of being shot down.
