The G grade is the quality, lower number=higher quality and more uniform roundness. Honestly the stocks are probably like G100 soft and lumpy crap so almost anything would be better. I have used G25 stainless steel and G5 ceramic and although the ceramics roll super smooth in your hand they are like 10x more expensive and you can't tell the difference while riding the bike. I recommend the G25 stainless ones.

Supposedly according to some people only some clutches can take the larger 1/8" without binding, but I have done 9 clutches and every single one worked perfect with the 1/8". 5 were from defective CDH/Zeda clutches from late last year and 4 were from new non-defective ones I purchased online.
I found 100pcs of G10 1/8" chrome steel bearings for even a cheaper price, I did a quick research and seems that copper grease
is the best for this application

I used high pressure grease from case and expect it will do well. Use it on the equipment at work.

Don't use chrome steel bearings. You want stainless - chrome plated is what the stock crappy ones are, although I'm sure the ones you found are better quality steel its still not worth whatever the small price difference is. I think I paid like $8 for 500 of them, which is enough for 9 clutches with plenty to spare. Buy them from a real hardware/lab equiptment vendor so you're not getting mislabled knockoff chinese crap. I wouldn't be surprised if some of the curiously well priced G10-G25 ones you see online are just G50 chinese knockoffs.

I just used a thin layer of some generic moly-graph lube from a big old tube I've had for years. Its marine quality graphite+lithium grease that is water and pressure resistant, won't melt at most normal operating temps (like 350* or something), and is meant for use in bearings.

Excelleeeent they has already shipped them, oh well, I guess that I'm going to have some great times with my sling 🤷‍♂️
I will check to my local mechanic store, maybe upon asking them, they will throw a bucket of bearings at me xD
I probably have some good Valvoline grease in the workshop, I'll have to check

Honestly I would just run em then and keep an eye out. I can't imagine there is any way possible they could be WORSE than whats in there lol.

I can test the quality of the bearing themselves by torturing some with an hammer, generally if they are crappy they fail pretty quickly.
Oh man what the hell there's inside those clutches? The marbles used by kiddos at the seaside? Ovo
