I have generally found lazy jacks to be a pain in the butt as it makes it harder to actually flake the sail or install a sail cover. I currently single-hand a 28 footer a lot and I suggest that it may be easier to single-hand without them. On most boats if you come to a stop and put the helm hard over, the boat will slide sidewards abeam to the wind. I find it easiest to flake the sail while standing on the leeward side of the boom with the sail on the windward side of the boat. Before you install the lazy jacks I suggest that go out and try that.
