Yes, parting line height is the primary factor that determines stability. Since various plastics cool differently, you’ll tend to see a trend in the stability (PLH) by plastic type. Other factors such as weight distribution, which affects gyroscopic stability, and airflow over a particular material of plastic also contribute. With that said, some molds and runs are simply just exceptions to the rule. For example, I’ve found the Eclipse Crave to be less stable than most of the other plastic types that the Crave is offered. That’s almost never the case. One last point, while the overall weight of a disc matters (when significantly different), the PLH is still a much more significant factor.
Great advice! Thanks for sharing. I am by no means an expert but wanted to do some backyard science. I’m curious to get out and do some more testing but obviously PLH is a significant factor here.
From my experience, Innova goes DX, R-Pro, G-Star, Star, Halo, Champion in terms of least to most-stable. There's also the durability considerations at the bottom-end, since those discs get beaten-up a lot more easily. There are also a lot of other minor factors that make this more of a general guide rather than a law. Edit: I don't include the Blizzard plastic, because the disc is also a lot lighter so that's two major variables in play.
I’m really curious now to compare somethings, like throwing the same discs, same weight, same parting line, but different plastic and see if there are any differences.
As always, it's a great video.
Appreciate that! Going to do a deep dive soon as I’ve already learned so much!
great video! such science!
Some science anyways. Hoping for some more from some smart comments here!
