Discs are different.

It is an artifact from the injection molding process. This unintentional feature is commonly called “sinking” and occurs at thicker locations on the part’s geometry. Ideally, injection molded parts will have a uniform sickness across the entire part… But discs have a thicker section at the rim. This thicker section is where the sinking occurs. This artifact is caused by unequal cooling times due to the wall thickness variation.

Yup, I’m a nerd.

Iím amazed Innova hasnít added a letter designator like C or something to the runs where itís more pronounced. And call it a feature instead of a flaw they just ignore.

Maybe itís just that I donít handle too many different molds but it seems some are more susceptible than others. Like it may have to do with the spacer?

You just saved me from having to type pretty much exactly that!

That works if you think Innova cares about quality or defects. They clearly don't.

Thatís kinda my point.
Oh damn these rims flare out way way past vertical. Oh thatís ok we will call it a ďplusĒ rim and sell it as a good thing.

Hey look someone effed up and put a leopard bottom on this run... oh we will call it an L version people will love it.

Wow our molds are getting old and all our discs are coming out overly domey we should fix that.
Nah we will make some new ones but keep using the old and the new we will call ď3Ē molds and change the flight numbers that way people will buy both.

Here is a blue eagle im going to send bag bubble in middle of disc thunderbird has sinking plus nipple in middle. i got the yellow gummy eagle flat but has sinking should i send back?

This is normal. I don't think you have a case for replacement as your disc looks perfectly fine
