use SRAM cassettes instead of Shimano, they have much more linear ratio gaps
I've just bought a couple of SRAM cassettes (fucking SRAM!) because (I think) they are all steel, whereas the Shimano cassettes have the two lowest gears in aluminium which wear out before the rest of the cassette.
If anyone knows where to get the lowest three cogs on a Shimano MTB cassette as a spare part, I'm all ears.
