But I thought the consensus (ha!) was that flange width didn't make a
significant difference, aerodynamically?
Wouldn't narrower flanges also make the wheel more flexible (smaller
lateral bracing angle)?
Woud such a wheel make a good "everyday" training wheel (with the
occasional race) or would the wider version be better? Wider version

keyword: "significant".

yes. marginally, for two otherwise identical rims and spoke counts. if
the rims or spoke counts are different, all bets are off.

wider is better. that wheel is for the purpose stated - time trialling.
would get you to you coffee shop ok though.

'Significant' is the key. Significant time loss if the wheel goes to
hell should be considered. Use a more standard wheel, the differences
are teeny, tiny.
