Well, I do bag them. So, what should I look for, higher parting line, flat, etc.? Is the Proton plastic more stable?

Wow, that response seems a little stronger than it should be.

Here is a video I created a month-ish ago. Ignore the "Plasma Volt" label I put on the gray disc. That is a Cosmic Neutron. I also mis-labeled the copper disc, that is Plasma. My bad, really wishing I had gotten those labels right. But you can easily see the flight differences between these discs. They were all brand new when I threw them. The weights aren't very different.

I think the Volts were very similar for a while but the new Cosmic Neutrons are very beefy. Almost "drop your Fireball or Motion" beefy. And this isn't just my Cosmic Neutron, everybody seems to think they are exceptionally overstable for a Volt.
Here is a thought about why they might be beefier:

MVP has been re-cutting/modifying molds so they can run them on their in-house machines. I have heard it said (anecdotally, grain of salt) that the beefier Volts are closer to MVP's original intent for the disc. Maybe they modded the new molds so the Volts fly "like they are supposed to?" Beats me, I have no inside information for this topic.

Even if that explains why the Cosmic Neutrons are so beefy, it doesn't explain why the copper Plasma is so understable. That disc has big turn.

So I don't have enough Volts to verify the "...Neutron and Proton flew differently..." statement. They seem fairly consistent but I don't have a large sample size. Probably only 8 or so and they are probably all from the same runs. My Plasma and Cosmic Neutron are outliers though. Those are definitely different.

If it were up to me, they would all fly like my Proton Volt <3 I have about 10 other Volts but they wouldn't add to the videos content. They are various shades of stability near the Proton in that video.


higher PLH, yeah. I only have 3 but my Proton is the least overstable. My Neutrons are slightly beefier.

As I've said before, I've been a toolmaker in an injection molding toolroom. I heard the interview when they were talking about this. They stated that they were NOT changing anything with the molding geometry. It's simply modifications of the outside of the mold, especially to get them to work on the different machines. I've done those mods. They are usually ejector system tie ins, locating rings, and nozzle geometry. I think I heard them mention doing cooling system upgrades too. None of this actually changes physical molding geometry. It might change cooling, which could in theory change PLH. So, new machines mean new/changed/updated processes which could, in theory, change honey a disc molds up. But nothing that they said leads me to believe they actually modified the molding surfaces.

Yeah, That was my understanding of the intent.
However, stranger things have happened. I have no special inside knowledge on what they did or didn’t do to the molds.

Me neither. Although, I'd love sneak in and snoop around that place....... michigan isn't too far away............ hahaha

I’ll meet you there :)

Like the raid on area 51...Only for plastic nerds.... Lol

I think they call it Gyro-palozza, or something like that...

Hahaha lol haha
