Message The stock size or undersize pulley is pointless?

I thought the main reason for a lightweight pulley is to reduce rotational mass (granted it does not provide damping, but have not seen evidence of this being problematic).

Also, I never really understood why an underdrive pulley is used if the recommendation (from you and others) is to use a pulley at the other end to correct for the underdrive.
