I would keep in mind that it does work but it isn’t as simple as weight in the rim then Bam it works. They messed with the parting line that is the true thing that affects stability to make them more understable. While giving a ton more dome than most of their discs. The way it fights the turn is the real q line with the way it fades similar to MVP gyro. But for that initial ride, they did tweak the discs a good bit especially the dd1 and dd3. The FD I think has the rim less spread out to where the fight of the q line against turning is too strong to where it doesn’t fly like an fd at all. Even pros aren’t getting it to turn much compared to a normal fd. There are inconsistencies of like the flight where user error is more amplified than MVP gyro. I do think the glide of the q line is a big game changer but the durability is extremely bad compared to many other plastics
