Grega is probaly on the money for ease and cost...The little SC12 or SC14 would be working it guts out and as several have said the fluroresin coated rotors would probaly "Expire" if pushed to hard (don't like big heat)As I stated earlier its personel preference.BTW the axial flow blowers are mechanically very inefficent but thermo/dynamically tops,45,000 Shaft horsepower on a RB211 (fitted to the Boeing Jumbo).
Have fun
P.S. It all eventually comes down to "MONEY".
