If you want the best beer possible I would pull some now.
+1. Pull off half a gallon or so and let it ferment in a separate fermenter.
You guys pushed me over the edge on that decision. I figured it would be fine to let it ride but thought pulling would net the best product. So I sanitized my siphon, took the cap off the bottom and siphoned off a half gallon of trub-filled wort. It's in a gallon jug in my lagering fridge. I plan to decant off the wort and use as my next starter. Killed two birds with one stone!
Thanks to all, as always!
