Steve - I tend to enjoy a bit of tartness , daughter has acquired I think (we both like really sour plums, for example). I've also got a Sunmist and its a bit sweeter (but its an older tree , as well -- I wonder if the stone fruits improve with the tree's age as it happens with figs). Im sure your varieties have higher chill hours than we can get down here -- that and , as you mentioned our subtropical humidity seems to limit us on some of the super sweet nectarines, apples,and peaches.
