***Which is better for storage?: Sackups knife protectors or knife rolls

[rogue_spear]

I am looking for suggestions on long term storage of folders.

Are Sackups Knife Protectors any good? They are socks for your knives; they are grey silicone treated cotton pouches.

Are knife rolls better for storing? Vinyl roll with leather tie straps, heavy cloth lining or velvet lining and a carrying handle.
