@fruitnut hank you for telling me about your experience with Gold Rush. We do have very hot summers here in central Georgia, but also get a decent amount of chilling hours...averaging around 900 the last few years.
Maybe that will allow it to grow a bit bigger than yours?
@alan Thanks for the reminder that hopefully a lot of the growth will be under my control.
Thank you everyone for your advice and opinions. I'll probably just go with the G30 and cross my fingers and see what happens. it really seems to depend on your location how successful it is, as there is a wide range of results in this thread.
