Default Stir Starter/2L flask - what size starter?

I made my stir starter today and got a 2L flask. I realize this is huge and way too big to do my usual 1 pt/ 1/2 cup DME. There is barely enough wort to fill the bottom of the flask. Obviously the vortex goes crazy on the bottom. What am I missing here?

Why such a small starter, do you make tiny OG beers? Have you checked out the pitching rate calculator at mrmalty.com?

I dissolve 228 grams of DME in two liters of water. Once dissolved I put the solution into the flask and boil for 5 minutes, cool and pitch the yeast. This give me a full two liter starter. No reason not to fill the flask all the way. Use some foam control to prevent a volcano and stir at room temperature.

This is why I use 1l and not 2l...
but in the end, it all makes beer, so do what feels good

Larger is better. IMO, a one liter starter isn't worth the bother. Foam control is your friend, nothing to fear.

FWIW, the 2 liter mark on most of the 2 liter flasks is considerably below the neck, so there's plenty of head space available in the event that it does get foamy. Even that is sometimes not enough, but I put the stir plate on a rimmed tray so the occasional overflow is very easy to clean up.
