Everybody has their own methods. Here's what works well for me. On meat that's gonna be cut up for hamburg I spend a lot of time cutting off all the silver skin, tallow, etc prior to grinding. It makes for some top notch hamburg.
But on backstrap pieces, roasts, etc, I let all the silver skin on and I don't vacuum pack red meat but instead roll each piece up tightly in saran wrap, then wrap in freezer paper. Trim off that silver skin prior to cooking and underneath is bright red fresh meat even a yr later. With the outer layer of silver skin, saran wrap, and freezer paper, it gives excellent protection.
