I would agree completely with what George said. As far as brands, I'm sure that some are certainly better than others and the concensus is that U.S., Canadian, or Japanese made chain is better than Chinese or Koren. I personally have all U.S. made grade 70 chain and binders, but I would not be afraid of using all Chinese made grade 70 chains and binders. I am not a metalurgist, and don't care to be, but you can find several sites on the internet that go into great detail of the steel making processes, but they also say that some metal made in China meets even the highest standards and some is junk. So, since I've spent so much money on my tractor and equipment, I went ahead and spent the extra $100 or so to buy all U.S. made stuff simply for piece of mind. The only thing I know for sure, since I personally experienced it, is that you can snap two "10,000" straps going down a highway dip with a 7500 pound trailer. I was in the 'straps are fine and are much easier to use' camp before that.
