I was wondering what you found the flex-head style of wrench useful for. I'm not talking about a flex head ratchet or a flex head box end, it's more like a socket on the end of a wrench...see http://buy1.snapon.com/catalog/item...2&group_ID=562&store=snapon-store&dir=catalog for an example. If you do find them useful, do you recommend the style with a flex head on each end, or with a flex head on one end and an open end on the other end?
