Count yourself lucky when your indexing decisions can be based solely on a single column. Like most things in life, context creates more value than content.

Consider the question "Is 300 horsepower good?" It will not put another man on the moon or move 12 railrailcars of freight. Give a Miata that much power and you'll end up with a lot of scrap metal; a Corvette, well...you'll want more.

Do not create an index for the sake of having an index, understand how and why the index creates value, and be very wary of diminishing returns.
