Glad you mention the red flesh of Arctic Glo. I looked up Dave Wilson. The pic was just like you said even though it also said it was a "white nectarine".
It is supposed to be mid season nect , late June to early July for CA. It is " spritely sweet. No wonder you like it so much. With that ripening date for CA, it will be in Sept before it will ripen here for me. Its skin already turns red now, very deceptive by color.
Arctic Star is a real white nect and early season, early to mid June for CA. I think I have a real Arctic Star, with white flesh, semi cling stone, low acid and very sweet. Those who like sweet fruit like me or @thecityman would love it.
It should ripen here some time in August. Even the one that I pick yesterday has brix at 20. I like it already.
