I went shopping for my Blizzard Boss after reading in this thread that Innova wants the bubbles to be relatively concentrated in the flight plate rather than the rim. I can see how they want the bubbles as small as possible as well, maybe even microscopic, like the air bubbles in Ivory soap. I would expect the distribution of the bubbles (how far they are from the center) to affect the stability of the disc.
So I shopped for a 150g Boss with visible bubbles in the flight plate, but I didn't want the bubbles too big, since I was worried about the plastic opening up where the bubbles are and forming holes through the flight plate. I saw a wide range of specimens in my local store, from no visible bubbles at all (probably microscopic) to big bubbles like you see from condensation on the side of a frosty glass of Coke. I saw them way out on the rim, packed into the flight plate, some of both, etc. I also saw a few of those extra-domey Destroyers in the store, and both the store's owner and I were curious about how that deformation affects the discs' flight. We only saw that in the Destroyers.
The Boss I chose was just over 150g with lots of visible but small bubbles (like fizz in a carbonated drink) distributed evenly through the flight plate. I also chose one with a relatively low "parting line height." I didn't want to go down to the 130-something discs, which I thought was a bit extreme for my first Blizzard disc.
Before playing a round, I threw it some in a field, and my first impression was the same happy amazement that others are reporting: EXTREMELY fast take-off and long glide that result in a significant and consistent distance increase over my other long drivers. My Blizzard Boss is definitely more understable than a new Star Boss, but I have a Star Boss in the bag that I have beaten to more understable than the new 150g B-Boss. My 150 B-Boss seems to take a line more like a 170g Star Valkyrie, but it goes farther with less effort. It will hold a suprisingly low anhyzer line for over 350' for me, but beyond that it tends to want to pull out of the turn. Its HSS is distinctly understable, but it turns over gradually and smoothly, rather than the hard flip you often see in something like a Sidewinder. It is also fairly consistent in expressing its LSS at the end of its flight, which makes it easier to trust than a more understable mold.
The only negative I have found in throwing this disc is that it tends to come out of my hand late. This makes it hard for me to throw a hyzer line with it, though I expect with practice I will get a feel for it. Otherwise I'm really excited to have it in my bag, as it opens up scoring opportunities on long holes that I didn't previously hope for. This disc makes me begin to wonder when the PDGA will start limiting the technological advances in disc manufacture. I would be surprised if the distance records aren't soon taken over by Blizzard discs.
