After digesting all of this and considering it and talking with a couple of people, I have decided that throwing them would not really be ethically wrong.
The key point that swayed my thinking was that new balls must be cleared by USBC and meet all of the existing rules before being thrown so while they may be different in some ways from some existing stuff they won't be exceeding the standards and therefore provide an unfair advantage.
The XCALIBUR, on the other hand, WAS different. And if I recall correctly balls weren't getting USBC stamps of approval before being released back then (correct me if I'm wrong.)
If I drilled something new and throw it and it does appear to be different and better in some way USBC does not regulate, I would feel differently.
Clearly, the NANO is not revolutionary in the way the XCALIBUR was.
So it will be in my bag.
Thanks to everyone for chiming in on this fascinating topic. You changed my mind and made me think in ways I did not expect.
