The actual vanguard choices would help, but in general you are sufficiently young (early 30s) to do 80/20. Assuming you're about 30 yrs out, Target Retirement 2050 is currently allocated at 90/10.
I would not allow the prior 10 yr returns to influence your choice to much, we have been in a declining interest rate environment for a very long time. This has bolstered the returns of 60/40 beyond what is likely a reasonable expectation looking forward the next 30 yrs. Vanguard has issued several letters/notes as of late trying to prepare investors that gains in the coming years are likely to fall short as interest rates begin to rise.
Lots of volatility in the market right now, probably a good idea not to focus on that for money with a thirty year horizon.
