yeah, those are A. arguta. both A. arguta and A. kolomikta are called arctic kiwi, though I guess arctic beauty kiwi would more specifically refer to A. kolomikta.
unfortunately, zone 7b/8 doesn't actually tell us much about your climate. for demonstration purposes, I'm in Western Washington and share a hardiness zone with a large part of Texas. our average minimum temperatures are roughly the same, but the similarity doesn't go much further than that. if you're reticent to disclose your general whereabouts, a slightly more specific description of your climate would do for our purposes here. in the case of arguta kiwis, they pretty much like full sun for best fruit, so it's less important than it would be with the kolomiktas. unless you get real intense sun and dry conditions, in which case even the argutas would like a bit of shade.
so, you say you got a pair. did you also get a male? I believe that whole genus is dioecious. some folks graft a male branch onto a female plant for pollination, but I've never heard of them being sold that way.
at any rate, be careful growing argutas on a tree. it's a vigorous vine. the shade of the oak might slow it down a bit, but it also might make it stretch for light and then put on weight at the ends of branches where it would cause the most damage. if it's a strong tree, you may well get away with it, but be sure to watch it. woody vines frequently break and/or kill their hosts.
