Terry can you post photos of the 2 varieties? I have 2 Brown Turkey fig trees, the dogs and I just came in from having a few of the fruit. I'll pluck a leaf and take a pic of mine too.
I didn't know the leaves were different among the varieties.

Check out Ray Givan's fig site, linked below. He's got some stuff on ID'ing the different varieties, based on leaf & fruit morphology.
Or, you could procure Condit's monograph, which is largely regarded as 'the Bible' among fig enthusiasts.

Here is a link that might be useful: Ray's Figs.
