The first run blizzards with the bubbles in the flight plate flew true to the numbers and much like regular champ, they just never ran those heavy (150g max?). If they did, I'd gobble a dozen up right now.
Blizzard doesn't hold the sweet spot as long as regular champ but my longest disc, if properly hyzer-flipped, is a 163 blizzard Wraith and since I only pull it out once a round or so (375'+ and wide open side to side or over the tops of trees), it pretty much stays put on that edge of usability/flippy since I'm never slamming tree trunks and usually landing soft with it but definitely falls under utility since it's so seldom used.
Been in the bag, in that state, for about 18 months now. I've tried Innova's speed 11's that start out less stable but I just don't have the consistency with them when they get to the same turn-over and/or flippy state as I do the Wraith.
