Probably em-dash in a formatted document rather than pair of hyphens like I'd use here. I'm pretty sure there are some stylistic recommendations about parens vs. em-dashes. I probably used to overuse parens but, in spite of being on my company's style committee for almost 15 years, I'm not sure I was ever all that consistent and I'm not sure we had hard and fast rules.
