Hubby and I are looking to open a 529 plan in Connecticut for our new baby. We think the age-based investments are too high-feed, given our taxable investments are all in VTSAX and the international fund. The lowest-fee option is the US Equity Index Option, which is a total investment in TIAA-CREF Equity Index Fund Institutional Class. Is this a worthwhile option in the eyes of other MMM'ers?
