That is a great question, but unfortunately there are no clear answers. There are many opinions, but the only reliable answers will come after the fact.
Pick an asset allocation that is comfortable for you, invest what you can, and things will work out however they will. As that 15 years becomes 10, 5, 3, etc., the +/- on your estimate will shrink, but even one year out there can be significant uncertainty.
