Okay, the 10 ball. This bearing is from one drop, and it has 10 steel balls, while normal bearings only have 8. In play, this bearing is amazing. It is way smoother than the 8 balls, not causing as much vibe, and almost dead silent. Only a little buzz. Kind of like how your computer sounds when you turn it on. In volume. The bearing also spins longer than a 8 ball, or at least to me. Flicking the two bearings, the 10 ball easily spins longer, by around 5 seconds. Pros and Cons time I guess!
Nothing, but I guess it isn’t a KK. Which is a good and bad. Because compared to a ten ball, KKs are screaming elephants charging into your house. But KK keeps the string away from the response, which also lengthens spin time. I have never used a KK, but I don’t plan on buying one because I like quiet bearings better, not a screechy one. Quietness is the only reason why I lube all my bearings, so I guess it depends on you.
Comparison of KK, 10 Ball, and 8 Ball.
KK keeps the string away from the side, but is loud. By keeping string away from the sides, it gives better spin times, and helps during multiple string layer tricks.
10 Ball is silent, spins longer, and is smooth.
8 ball is medium loud, and doesn’t have any real advantages, although I can get all my tricks done on a 8 ball, I like a 10 ball because of silence and smoothness. Like a ninja sneaking up for a kill.
