Don't even look at Shitmanos, in my opinion they should all be melted down before they do someone damage, my "XT" or whatever code it's got now snapped going downhill I'm yet to have any Sram chain snap on me and I've used the bottom of the range and almost top of the range versions. Any of them will do you good EDIT: forgot to add, the powerlinks are *really* useful in my opinion, but they are known to occasionally shake loose when freewheeling on DH. I've only had it happen to me once and that was on a really worn chain so not overly worried, I'll always run with one in but don't forget it's easy to leave it out if you wish
