The new discs are definitely interesting. I would have to say that the Ringer top is more overstable and in turn is more reliable. I really only like the Banger top for backhands as well. I did not like the feel in my hand for forehand shots. I use a get freaky crystal flex zone currently and a Zone OS, I would say that the ringer top is equally if not more stable than both of those discs. The banger top is more understable than both. I can find a spot in my bag for the ringer, but no banger. Hope it helps!
