explain your theory mathematically, what do you think gives it stability in flight?
Obviously, not many of us could explain things in true mathematical terms. It is a little silly to ask.
There are many things that are going to contribute to the stability of a disc. Design profile, environmental factors (wind), weight, weight distribution, etc. It's common sense though that all golf discs have added weight in their rims and less in the dish. Gyro stability in this sense is nothing new in MVP discs. The base (candy) plastic in the MVP disc plane appears the same thickness/density of comparable discs from other companies. If this is true, then the rim density must also be comparable to stay at the same weight. Therefore, it would seem the 2 plastic concept would not translate to much flight difference.
I'm not bashing their design. I own the discs, I love the discs. I think it is a very smart branding move to create a unique image and product (which is hard to do in this field). I love their candy plastic. I would like to see an ion or anode in 100% that plastic. It probably will not happen though because they need to stay true to their image.
The point you made about different textures in plastics adding to durability in the base and added "grip" in the rim to grab chains is much more of a true revolution in disc design. Glad to see them thinking outside of the box.
