G'day Mike,
Why not have a chat with one of your local nurserymen or
orchardists and find out what is the local drum. You don't tell us where you
are, and that would affect the choice of rootstock. Any way, they will
probably be happy to 'Bud' a couple or more of the peach for you, and others
in your family might like one of Grandfathers peaches (...there is some Xmas
shopping done already.. ).

...wishing you rain...
