Please help a newbie pick an apple tree!

I second the NovaMac recommendation.

I got two last spring. One on b9 and another i grafted to m7.

It was the only tree in perdue univ list of disease resistent varieties that scored VR (very resistent) to scab, CAR, fire blight and powerdy mildew.

There is a post on Novamac with details on taste recently added. I will try to find that for you and link below.
