Wings are a nice added feature for comfort and they do add to the righting moment. However, they do have their disadvantages too. As has been said, they are heavy (my SX wings are ~50 lbs). Also, as soon as you heel to the point where the leeward wing is in the water, you lose a considerable portion of your speed. In chop, the problem is only magnified. Also, depending on the type of wing tramp you have, the wings add area that wind can get under and potentially flip the boat. I've also found that my wings are fairly fragile. I've had them break several times in gentle capsizes (and once when I hit a channel marker, but that's a different story). Anyway, I do like the wings on my boat, but I don't know that I would add wings to a boat that didn't already have them.
