overwintering figs

I just got a small fig tree today and I'm thinking about how to overwinter it here in zone 5b. I know some people pack mulch around it with tarpaper or something, and some people dig a ranch and bury it every winter. Other people just grow them in pots and put them in a cool place for the winter.

There ideas all seem less than optimal for me. A lot of work an it seems hard on the trees.Does anyone grow figs in my climate? Does anyone have tips or advice?

My only tip is to dry out the site as much as possible, as in, dont water anymore. Figs hold a lot of water in their branches, and I have seen the branches literally burst like a copper pipe. Fig trees do have a lot of vigor though, so even when that has happened, the tree just resprouts lower down and continues growing the next year.

I'm guessing that a warm microclimate would be good. I wonder if large stones would help.
