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
