Maybe someone can chime in, as this is the only cold hardy variety I've experimented with (along with Wonderful which is not a zone 7 pom). The Wonderful dies to the ground every winter.
If I find some room I want to try Belbek, which is early, hard seeded, and VERY cold hardy below 0f. Would increase fruit set through pollination of both. Seeds don't bother me, I chew them or swallow them whole, good fiber
