As a recreational sailor, I have to agree with others that have shown a preference for wings. (I sail a H18M, with the shorter wings.) My wife and 7 year old love them. The wings really came in handy while crossing Tahoe last year when the wind kicked in hard and there was 3 foot chop. As a racer, my experience has been thus: 1- In really really light air, thank goodness I've had them - great paddling platforms, 2- in moderate air the wings are 40 lbs extra and don't add to performance, 3- in really good winds (20+), the extra leverage really allows you to push the boat hard by keeping it flat and ultimately results in less depowering while heading upwind, and more rear leverage when flying downwind.
In the end, check the conditions you sail in and contrast that with the type of sailing you do. Hell, you can always take those loungers off in 15 minutes.
