Manufacturing Inconsistencies

BlitzDG on YouTube brought up a topic today that I have been extremely frustrated about, and am curious what others think. He mentioned manufacturing inconsistency as an issue when it comes to buying discs. You can buy two different runs of Innova Champion Firebirds and they will fly completely different, even though they are advertised as the “same disc”. Picture one are my 2 Innova Rollo’s, left is brand new champion with a slight dome top, right is thrown about 30 times DX with a flat top. The parting lines are completely different, with the champ having a higher parting line which means it is more overstable (it’s disc physics). This is before taking into consideration that champion plastic is generally much more overstable than DX plastic. Is my champion Rollo even a Rollo anymore since the disc measurements aren’t even proper? Picture 2 are my 2 Teebirds, left is a champion 12x kenbird, right is my beat to perfect DX G-Bird. Again we have a fair inconsistency in the parting line, with the DX being lower than the Champion, again making the Champion even more overstable before accounting for the plastic difference. Picture 3 are my 2 new Champion Teebirds, left being the kenbird, and right being a metal flake bird. This is the only time consistency actually shows, so these discs should fly extremely similarly and be interchangeable without looking.

The BlitzDG video found me after watching a different YouTube video on the manufacturing inconsistencies of the MVP trail from run to run, uploaded by Brook Arnold called “Not All Trails Fly The Same” where she throws 4 different trails and gets 4 different flight paths. In this video she shows that each disc as a slightly different parting line, not to mention different plastics which may also effect flight characteristics.

With all this being said; Is anyone else mad at disc manufacturers with their inconsistencies? Why can’t we throw a brand new 2024 champion Firebird and get the same flight as a Champion firebird from 2016? Why is MVP, the brand that players considered to be perfect with their production runs, starting to produce inconsistent products? We as players should be able to pick up a disc that is the same plastic, same mold, new production run, and get the same exact flight as the first run discs. What does everyone else think? Are BlitzDG and I alone in this thinking? All opinions welcome!

TLDR; How many more bad runs of good molds do we have to endure before disc manufacturers start producing a consistent product from run to run, year to year?
