We rolled over DH's previous employer 401k to Vanguard and I'm wondering if we should just put it all into VTSAX or if there are other funds we should consider. Right now, he has his IRA all in VTSAX (admiral shares of VTSMX), and basically all of the rest of our investments are in FUSVX (Fidelity's version of VTSAX) or VIIIX (institutional shares).
Basically, if you had around $30k to throw into Vanguard funds today, what would you do and why?
If it helps, our goal is to be able to cut back to part time or fully retire in around 10-15 years. We are both 36.
