What I did was figure out the gear inch range I use mostly and see if a different cassette could accomplish the same.
BikeCalc.com - Bicycle Gear Inches Chart. If you input all you gear here, you can see your existing range and then play around with what other options might give you.
I never get out of my 52t chain ring but that's because it is mostly flat or small hills where I ride OR I ride big hills and use my e-assist (and the 52t is barely big enough to avoid spinning out on flatter ground). A triple is useful if you ride a varied terrain with everything from flats to big hills because you need the granny gears to climb (manually not electric). So what is your terrain like? Pretty consistently flatish?
