As someone that has thrown a metric crap ton of Innova, Trilogy, Discraft, MVP, etc I wholeheartedly disagree with the notion that Trilogy's premium plastic is clearly inferior or less durable than Innova, etc. All discs break in with wear. I've had Innova discs "get flippy" just as quickly as Trilogy discs; it's probably dependent on the mold. Trilogy might break in a scooch faster but I doubt it's quantifiable to be honest. Even then, once the disc breaks in it stays there so even if you think Trilogy discs get too flippy you just have to pick a mold a bit more overstable than what you're looking for, like cycling DX discs except not as extreme.
I'd get some new discs from each company and slam them into walls after each throw to artificially simulate all this but it wouldn't solve anything b/c people refuse to budge from their positions anyway.
