Anax, pull a Late-war plane at random out of your hat. I can guarantee you that 99% of the time, if it can't maneuver on fairly equal terms with a SpitXVI, it will be at least as fast or faster. The same cannot be said for the Lala or the SpitXIV.
You must understand of course, that as far as I'm concerned HTC *could* perk the SpitXVI lightly, 3-5, about the same I'd assign to the La-7. And lower the SpitXIV's price to the same amount, perhaps.
