Re: Klingon Bird of Prey (whichever class)
I'm not entirely convinced of the story that Gene was deliberately trying to screw FJ, as I'm tempted to say the "even numbers" rule may have preceded the publication of the TM and may even have originated while TOS was still in production. But I could be wrong on that as well. Personally I agree with you, and I think one could easily say even pairs is a more optimal arrangement for making a balanced field or achieving better speed. But I see no reason why odd numbers couldn't be useful.
