My thoughts are to take a 12-25t cassette, and an 11-32t.
Like the idea of single tooth increments from the 12 so 12-13-14-15-16 and was wondering if using a 17 but then going to 20-22-25-28-32 - would the 3-tooth strep between 17-20 be too big? - i note of course that 22-25-28 are also 3 tooth increments, with final 28-32 being 4t difference.

I could use the 18t instead which would be 16-18-20, but i have a feeling that 17t would come in handy for my riding/cadence/road-speed.
It’s for a road bike, variety of terrain, some quite lumpy hence the desire to go to 32t.

Appreciate any thoughts.
Thanks,
