Your 401k and your DGI portfolio?

[ken-do-nim]

For those of you 59 and a half and older, what has been your 401k withdrawal strategy?  I ask because I'm wondering if, even though I keep working into my 60s, whether I might pull a substantial amount down annually to feed my taxable DGI portfolio.  Or if it's better to start pulling down 401k money only after I retire, if before the required minimum distributions kick in.

PS: I turn 50 in a couple weeks, so this is looking way in the future.
