I love privet :-[, particularly the golden privet & have propogated twigs which now grow here and there as untrimmed shrubs - lovely golden blaze all through the year. We're on heavy clay soil and part of the garden is v. boggy....it grows well. Only needs cutting twice a year, so no hardship there.
If I'd got a plot to hedge and it was free, I'd go for it, give it a try anyway. Nothing to lose and you could always rip out parts & replant to create a mixed hedge later, if you wanted?
