Me too, which is why most of my conlangs use one.  Either that or
base-6.  An early draft of W's numbers used a base 24.  An early form of
Proto-Kassi-Plia [ancestor to Watakassí) used a base-6 system, but early
on borrowed the numbers for 7-12 from another language.  Indeed, many of
PKP's relatives did the same, which is why in comparing branches of the
Kashic family, 1-6 are found to be related, but 7-12 are not.  In fact,
the word for 11 in PKP couldn't've been native, it was _'inú_ - the
glottal stop was a foreign phoneme.

I just use A and B.

Did they actually use separate roots for all those numbers, or was the
sexagesimal system purely a writing convention?
