When do you use your Wii strap? I've never had it slip or anything but I always use it during WiiSports (except golf) . I don't use it during Zelda or when browsing menus/Miing/messaging/etc. If I got a game like Wario Ware I'd probably use it too. I always keep the strap, though. The only time I connect it through the attachments is for boxing, though.
