The soil here is much different than there - we have clay, you have sand. You should speak with someone who is also coastal, in either GA or SC, possibly NC.
The best persons you could reference would be F4F member 'snaglpus' (Dennis) who is still around today, and also Ray Givan who is an expert on the topic of figs and he used to live around the corner from you. Read the first page of his website, then click through on the 'my collection' link to review his notes: http://www.raysfiginfo.com/
PS, if you are in town, I can tell you where at least one pair of trees are that I was very interested in! I found a couple of trees last time my DW and I were in town (we love SAV, got married there, run away there every so often).
