When I have a lot of gear choices, I like very close ratios on the middle or cruising range, with much less-considered tailwind and downhill gears and ditto climbing gears. On my sole derailleur bike* I use a 42/28 X 13-25 10 speed and I'll probably one day swap the 28 for a 26 o 24, and the low 25 t (13-20 corncob + 22 + 25) with a 26 or 27t.
The current 42.28 X 13-25 gives me nice 1-t jumps between 95" and 50" in the mainstream 42, and down to 33" in the 28 (29 1/2" diameter wheel). With a 26t granny and a 26 t big cog the low would be 30"; with a 24/27 it would be 26". I climb by low-cadence torqueing, so 26" and even 33" is far lower than I need even in my old age for any hill I encounter in the terrain and for the sort of riding I do. I do 99.9% of my riding in the 42 (low 50"); terrain is either sandy flat (No-So) or rather steeply rolling with some short and sharp and some long and gradual climbs (E-W). If I wanted to use a long cage instead of an 8-sp short cage rd and 11 or 12 speeds, I could maintain the essential crusing range 6 or 7 1-t jumps and increase the range to as much as 100" to 20". I've built nice-working 10-sp cassettes from a mix of 7, 8, and 9 sp cogs + 1 or 2 Uniglides, but my 13-25 is built from Miche Shimano cogs, outer + middle + inner, and these shift even better. Using an 11-sp chain makes shifting the best I've ever used (as good as the Am Classic stock 11-23 and 12-25 10s I used a decade ago) and only ceding first place to the 7-sp Uniglide Sante drivetrain on my late 1989 Falcon. *Out of 4; the other 3: fixed gear gofast with 76/67" flip flop gears, ss mountain bike -- 65" for flatland sand, and AM hub errand road bike: 72/65/56".
