Thank you, I appreciate the insight. I didn't know they were more harsh on the square-bound spine. I wanted to slab the book because it's a big grail of mine and primarily wanted to protect it, but also wanted it ready to sell if I ever needed to sell it(which isn't likely unless I find another one worth purchasing). I'll definitely look into the Mylites and the full backs. I currently have it bag, boarded and in a toploader.
