As you like.
I prefer the Diskeeper sleeves. They're heavier and more rigid than the MFSL sleeves, so they're easier to get into the jacket. They're all around just better, I think.
But they're only intermittently available on Amazon for some reason.
Sleeve City has always had them in stock when I order.
I have had great results with Bags Unlimited/KAB polylined innersleeves. For many years now...
