Were you 48-36?
BTW, what did you learn about the chain sizing?
Uh, I used to run 82-72 chainrings, but now that I'm a year older I don't have the knees for it. So now I run 48-34 (after running 48-36 for a few decades). I like hills too because I have the gears for them but lower gears means not doing them as fast as Zipp.
Harris Cyclery says this about the SRAM PC-870:
Works with all derailleur systems except 9-/10-speed, including Shimano HG and IG. Includes a "Power Link" re-usable master link.
This is our main recommendation for bikes with 5-, 6-, 7- or 8-speed rear clusters.
From what I read in BF, the SRAM chains PC-830, 850, 870, and 890 are similar but differ mostly in what parts are nickel plated. The 870 got several recommendations from BF members as the sweet spot in the price range. It also comes with the SRAM Power Link, not a big deal considering how infrequently I separate a chain link but a convenience every so often. So that's what I went with. It sure looks pretty (still in the box), not like the old Regina gold chains but still bling-ish.
