Alan,
This shouldn't be happening on an FW. My FM has this problem, but
that may be normal as there seems to be a complicated load path in low.

I used to run 22-19 which perfectly split the ratios on an AW. BTW an old Sturmey 22t cog won't work in this application. Tooth shape is odd and chain can skip if there is a derailleur in the system.
Another possibility would be to use two wider ratio cogs to extend the range of your AM.
I recently put 24-18 on my FW, using a 24t modified Shimano
pre-Hyperglide cassette cog, a 1mm FW/BB spacer and an 18t Shimano Nexus cog.

Your Cyclo should do OK. The hard part is finding a derailleur that has limiting screws long enough.
My favorite RD for a hybrid is the Huret Svelto. It's clearly not modern and it would seem odd to have anything bulkier working only two cogs.
I think a good rule of thumb would be to use one cassette cog and one dished with a modern 1/8" chain like SRAM or KMC. Use 2 dished cogs with older, wider 1/8" chains.
