Im only a few days into owning my new-old 3DS XL (fully hacked, waiting for a flashcard!) and already my hands are protesting! I've read in at least one other thread that cases, shells or covers might make the system heat up. But I've been playing a few actual 3DS games and the system doesn't seem to get warm at all! So if there really isn't any issue there I would like some sort of extra grip. I was looking at these - Any opinions? Better options? Remember: This is an OLD 3DS XL!
