VTRIX is also actively managed. I would think you'd want to go with a blended index fund, such as VFWIX (or VGTSX). If you then wanted more of a value tilt, you could then use VTRIX (or an index like EFV). Keep in mind that both VGTSX and VFWIX also include EM, so you'd have some duplication if you keep holding EM seperately.
Also, for an idea of how your holdings are diversified in international, I'd recommend using portfolio x-ray on morningstar. Here's the link:

Something else to keep in mind is where you hold these funds. Is it in a taxable or sheltered account? If it's taxable account, then I'd recommend VFWIX (or its etf, VEU), since you get the foreign tax credit.
