If I was planting another Grape I would likely try one of the new Univ. Arkansas releases Hope, Gratitude, Joy, and Faith. As new they don't have the track record of some, but for the Southeast grower they have a pretty good program for disease resistance. Mars is seedless and from that program a good proven choice. Jupiter is an interesting grape from the same program. The new releases depart from the celestial naming of their prior grapes and Stark Bros has starting carrying them as one source. I have heard good things about the aforementioned DoubleA vineyards as well.
My Hardy Kiwi are very slow. They as well take up a lot of space. A couple of my females have bloomed the last 2 years but my male has not, so maybe this year. Issai does not reliably set fruit without pollination. It is a smaller vine and mine would set fruit and drop 99.9%, and many other folks report the same issue.
