Which Chain is stronger?
Sram PC991 Cross Step, or Sram PC991 Hollow pin?
Trying to decide which chain for my LHT.
Stronger, as in which one would be less likely to break? I advise not worrying about it, I've used SRAM nine speed hollow pin chains for aggressive off-road riding, never had a problem. The only real difference is the weight, and even that is just a few grams. For a touring bike, I'd just go with the less expensive model since you're probably not concerned with a tiny bit of weight savings. If you like SRAM chains (and they are excellent chains), just go with the least expensive nine speed model, strength is a non-issue-

+1 to the comments from well biked. If there is any durability issue, the hollow-pin may be less durable - but I doubt there's a meaningful difference here. SRAM's lowest-level chains don't have nickel-plated links, but I think that only matters because they end up being more susceptible to rust, which isn't very meaningful depending on your riding conditions.
