You should be able to get all Spartan Index funds, I like Vanguard but nothing wrong with Fidelity either. I would not pay to trade Vanguard funds if I had access to the Fidelity's Spartan funds for free.
I'm not crazy about a small value tilt but many like it. I looked at it as I'm getting older, the years from now to retirement are becoming less, most of the cash I have in the market is my latter working years and the most important part is I don't think mentally I could watch small value under perform the broad market for years and not kick it to the curb.
Put it another way, watching my portfolio under perform the broad market 10 years before retirement was something I was not keen on watching. The flip side is true as well and I understand that I could have done better and I'm ok with that. Small value investing is a very controversial topic, be sure you understand the theory behind the Fama French model and the data set they used. As the saying goes know what you are investing in and why.
I applied the same school of thought too Slice and Dice.
