Hi Kris,
You can use Sirloin Tip, Eye Round, Top Round, Bottom Round, and any other "Cheaper Beef", as long as you slice it real thin, and keep it about Med-Rare.
If You have an SV you can do an Awesome Eye Round at 132° for 21 hours, and you won't have to slice it real thin to keep it "Fork Tender" for your Sammies!!
