VPI Scout drive belt differences

Does any one know what the difference is between the original clear color drive belt and the Black Tranquility™ drive belt, other than price difference of $20 versus $30 respectively?

Mine came with a black belt when I originally purchased the TT new.


When i had my Aries 3 the black belt was best IMO. Do a search of this topic for a lot more info.
The black belt has carbon added for less static and lower noise.

Thanks all for clarifying! I will be ordering the black belts!
