Their own 301 powered machine did not produce it. Something to do with cropped compressor blades, as I remember it.
Also, IIRC, the 201's would accelerate (spool up) faster than the 301's, so if you needed lots of power quickly, the 201's would be better.
As far as I can remember, the howl is equally apparent on both engine types.
Now, if only they would get the Rapid Start system functioning, that would really wow the crowds.
