Pitching rate for 10gal Lager

I'm making a 10gal batch of Marzen OG 1.055.
I need about 4L of starter. I have 2 x 2L erlyenmeyer flasks, and stirplates.
Here's what I'm thinking. What are your thoughts.

1. Pitch 2 vials of yeast into a 2L starter and grow to saturation (mr malty says it will require 2 vials into 1.3L starter if doing 5gal).
2. Split starter into 2 flasks, top each off to 2L and grow again to saturation.
3. Let yeast settle in both, decant liquid, pitch slurry.

Also, fermenting temp for yeast is 50f. I know everyone has different thoughts on starter temps, I'm thinking these starters will be made around 55f, unless anyone has other ideas.

Looks fine, but pitching two vials is wasting money in my opinion. Pitch one. Save the other one.

This. Just build up your starter a couple times.
