The PG1170 arrived earlier, and I just installed it between meetings. No need to adjust the limit screws, and almost no hesitancy going up/down the cassette on the stand - where the Miche would only reluctantly get into the 29T, the SRAM easily engages the 28T. I initially thought there was some hesitancy going from 14T to 13T, but it turns out there just wasn't enough chain speed - cranking a little faster cured that. All in all, on the stand, at least, the SRAM PG1170 shifts better than the Miche Light Primato. We'll see how she feels when I get to take her out again.

From a design perspective, it's interesting to note the differences between the cassettes.
- The Miche has 11 individual cogs, the SRAM has the biggest cogs mounted together.
- The Miche has plastic spacers, the SRAM has alloy
- The Miche requires you to compress the plastic spacers with the lockring to get the last cog to fit. The SRAM's smallest cog doesn't sit fully on the freehub body either, but with freehub grooves that don't go all the way through + alloy spacers, I doubt there's any meaningful compression going on when I install the lockring
- The Miche is matte, with an alloy 29T; the SRAM is chromed and presumably the same material throughout.

With alloy freehub bodies being common, I would've thought it would be more common for cassettes to have cogs on a one-piece carrier to distribute the load better? I can definitely see thin individual cogs biting into freehub bodies over time.
