Almost every day when I ride my rando bike with no gear on it, I use the 30T granny ring on the triple. My derailleur touring bike uses a 24T granny instead of the 30T that came on that triple. Both bikes use 11/32 eight speed cassettes.
But, you have ridden a Sherpa, you presumably know what gears you used to have but will never need again.
