Kat, from that pic I can tell you that strap is NOT 66 feet long (if it was it would be about the size of your spare tire when wound up like that). ARB is a very reputable name in off road and make nothing but top quality stuff so you can't go wrong with them. As far as doubling a strap...yes you can if you need a shorter strap for recovery. You don't gain or loose any strength. And even if it says it don't stretch it will to some degree...its just the nature of the material. Some will just have more elastic property than others depending on how they are made.
