@dblast I’m familiar with soft sleeves vs deck protectors. If you want you can read this article I wrote 3 & 1/2 years ago so you can see I’m not unfamiliar. But it seems like you already have your mind set so I’ll let it be at that… Use what you feel comfortable with. I’ll save money and further complication by just using penny sleeves.
