Do you double sleeve your decks? Why / why not?

I don't have that much first hand experience but here's a quick literary review of random internet posts:

Pros

• Cards are protected from liquids
• Keeps foils planar
• Top part of the card is protected from dirt
  • Is this really such a problem?
• Some people like the shuffle feel
• Cards remain single sleeved when you remove the outer sleeves and put them into a binder

Cons

• More costly
• Thicker decks, especially in 100 card formats
• Deck boxes become tight, trouble fitting tokens etc.
• Shuffling may become more cumbersome
