I think the Dura Ace and Campagnolo track cogs go down to 13 T. (I even have a 12T Campagnolo, but it seems to have a smaller diamerter than the standard track-hubs.)
The 13T cog will give you some more speed but probably still not enough. I ride 13Ton 54T on
my Swift what I find very convenient.
You guys must have massively strong legs to be pushing such big gears. When I first rode a fixed gear, I started-out with the recommended 70" gear, then went to a 67", and now I'm at a 65" with shorter cranks (165mm). Either that or I guess you both live in relatively flat areas.
