Trying to understand what is so bad or good (how you look at it I guess) about Formula hubs compared to Profile, White Industries, Phil Wood, American Classic, etc. which all seem to be double or triple the price.

Do Profiles roll 2 or 3 times smoother? Require 2 or 3 times less maintenance? Or weigh less?

In addition, on formula's page, they list something called the "Mechanism:" and there's an option called "C+C" or "SB"? Does C+C mean Cog plus cog and SB means single bearing (meaning you can only put a cog on one side)?
