So I noticed this: https://imgur.com/a/Oek6EDn
Takara Tomy 7's are on the left and Hasbro 7's are on the right. Hasbro's are definitely a little lighter due to being just a little bit more hollowed out, so I decided to test how that would effect Stamina (The most common use for 7)

Deep Chaos 7(Takara Tomy) Revolve
1.     1:58
2.     1:55
3.     1:46
4.     1:49
5.     1:54
6.     1:53
7.     1:52
8.     1:57
9.     1:59
10.  1:52
Average: 1:53

It's not that much of a difference in the average, but I was able to get higher spin times with Takara Tomy's

So in theory hasbro discs would have a bit better burst resistance?
