Ethics:
  1. A set of principles of right conduct.
  2. A theory or a system of moral values
It all depends on who's writing the rulebook...not sure if its fair to call it unethical in the least.....I'm not really "into" hybrids or anything else like that, but who am I to judge someone like kevin whose very livelihood depends upon his reputation in the industry and the eye of the public.
