Tanky I haven't built either, but I know the Hasa kit is fairly old, while the Academy kit is relatively new and supposed to the best of the breed in 1/72. Not sure if anyone has compared with the Tamiys offering though. See link below:

Sounds like there isn't much between the Tamiya and Academy kits, apart from price.
Jay I'm starting to think you're suffering from 'Airfixation', an almost incurable addiction that leads the aflicted to repeatedly spend their money on mediocre British kits from the 70's. Please tell me this isn't so?
Joking aside, at least this is a smal project, so the amount of work required should not be too onerous. Either that, or you splash for the Academy offering, after all you don't want to waste those lovely AM decals!!!
Tom Nice choice on the Fw190 camo! The winter white wash scheme should prove a challenge.
