All 4 of those ETFs are the same asset class: US Large stocks. Buying all 4 of those is unnecessary overlap. VTI is the best one for US Large stocks.
If you are going to use more than 1 fund, you should use other asset classes: US small, International, Emerging markets, and so on. Try
this thread for my discussion of what kind of losses you can expect, and which asset classes to use.
