Sram 9 speed chains, 3 models, differences?
So I am trying to get a replacement chain for my Surly LHT.
Surly list the chain as a SRAM PC-971, but the one I bought is about 2 links shorter than the one it came with.
SRAM list three chains - PC-991, PC-971 and PC-951 but their site gives no information about them.
Does anybody know the difference between them?
I would prefer to buy one too long and take a couple of links out, giving me some spare links, than add links...

Assuming I remember correctly
951 is their basic chain, nothing special but still works well, the one on my xtracycle is over 2k miles with plenty of life left.
971 has a nickel coating that makes the chain look much more polished and supposedly helps a little with rust prevention
991 has two models, one has hollow pins to save a little weight, one is their cross step pin which is supposed to be a stronger riveting method. This chain also works well, I got a lot of use out of the one on my mountain bike but I really doubt it is worth the cost over the other two.
