Who would you guys roll with?

Markstrom @ WAS
Allen @ PHO

I lean towards Allen because of matchup and defensive system but think I wouldn't mind rolling with Markstrom if he gets the call to play back to back (tonight @ WAS and tomorrow vs WPG). What do you think are Markstrom's chances of the back to back?
