My guess as being a 51-B driver 90% of the time, is that Trash and Kingcobra have never even flown a B-model. You both need to give up, as many have said the only real difference is point of origin.
Some 51 drivers will fight it out, I enjoy the low and slow fights in the 51. Its very gratifying for me at least. IMO those who do complain about BnZ tactics have yet figured out how to counter them.
As I have stated before, I'd love to see the Allison Powered 51 in AH, but no cannon birds.
