Would give my eyeteeth for a P-47M. I don't think it would REALLY need to be perked in an arena that has unperked La7s and Spixteens, however, the fact that the USAAF needs a perk plane is perhaps one point in its favor.
As another Jug option, nearly all Ds in the ETO were tweaked by their crews to be able to pull 72" on the manifold in emergencies. This would be a nice perk option, as well as paddle-blade props on D11s.
A D11 with a paddle-prop pulling 72" might be the fiercest jug of all.
