In Japan one of the pros shamed me for using the Izumi V. He said, "why do you use that? Because it's gold?", then showed me the FULL GARBAGE CAN of chain take-off from the other pros– all the much cheaper $15 black/blue HKK chain. "The only difference is the color, save your money".
I'm of the opinion that because we change our chains fairly frequently to avoid prematurely wearing-out our pretty expensive chainrings and cogs, that the chain does not need to have crazy expensive coatings on it. I just get the $15-20 chain, and change it often.
