Thanks to everyone on this site for all the amazing advice and help. After lots of back and forth, and assessing my actual risk desire and overall long term management of a portfolio I have settled on the following:
20% - VTSAX - Vanguard Total Stock Admiral (split btwn taxable and SEP IRA)
20% - VSIAX - Vanguard Small-Cap Value Admiral (in SEP IRA)
40% - VTIAX - Vanguard Total International Admiral (in taxable)
20% - VBTLX - Vanguard Total Bond Admiral (in SEP IRA)
I am going with all mfunds so I can put future monthly contributions on autopilot and not have to look that often - can always switch to EFTs in the future if so desired.
After a lot of reading, I decided I wanted a bit of small-cap tilt but keep the portfolio as simple as possible, so since Total International includes small-cap and emerging, I decided adding a small-cap value component to my US allocation was the desired amount of additional risk/tilt with out any added complexity and it adds a value component that wanted.
The result I hope is a pretty well diversified and very easy to maintain/balance portfolio.
I am lump-summing in with current low 6 figure funds and then on automatic contributions from there.
Now to write an action plan down, sign it and stick to it!
Any additional last thoughts/advice???
