Forget straps!!
A nylon 24mm rope 8meter is perfect because if you half it 4 meters is usable! They are about £40/45 but I've had my first rope for 8 years and God knows how many times it was abused and used for recovering comp motors that was stuck weekend I weekend out. A strop, a lifting strop is for winching about as good as a chocolate tea pot of something is really stuck.
