If you were 28 what would be your 2-3 fund portfolio % allocation?

Leaning one of these two but open to hearing more! I do not have any debt by the way and I max out my retirement accounts (IRA/401K):

• US Stock Market Index Fund (U.S.): 85%
• Total International Stock Index Fund: 10%
• Total Bond Market Index Fund: 5%

or

• US Stock Market Index Fund (U.S.): 80%
• Total International Stock Index Fund: 20%

Currently 100% in VTSAX but open to adjusting.

edit: I have a fairly high risk tolerance and I don't ever panic sell. I've never sold any of my VTSAX

edit 2: added US to the stock market index fund lines
