ats5g,
Thanks for the link to the Bogle presentation--his case for TSM rather than slice/dice is okay, though he has to throw out a lot of actual data to do it (basically, TSM performs just as well or better than a smal/value-tilted portfolio, if you throw out the years when value/small did better . . . hmmm) .
Still, I'm not hard-over on the value/small thing. My holdings in small and value are through Vanguard funds, which are a lot less tilted toward hard-core value stocks than are DFA funds. Costs are low, and I figure we're avoiding exposure to the stocks that have been bid up to stratospheric levels. And we have some $$ in TSM, so there's some balance there.
