I agree with this assesment. Under normal driving no big deal. But in an emergency manuever having it might provide the extra 10% you need to save your life. I'll keep using disconnects, and connecting them as often as possible. Offroad having it disconnected does help, but, it is not like night and day either - on easy or moderate trails I usually don't go through the trouble of disconnecting it (when new they went in and out pretty easy, but after years they don't seem to like going in or out as easily as they once did, or, I'm just lazy). I'm locked both ends so the extra 1" of travel not having a sway bar provides is not that big a deal. Take your sway bar off, see how much extra articulation it gives you, depending on the weight distribution on your rig you might be disapointed.
Bottom line on paved roads you are a little safer having it.
Off road you have a little more flex. Some times all it takes is a little bit to make the difference between getting where you are going and not.
I disconnected mine once to see what it felt like on corners. Could hardly tell the difference on curves and corners, even taken at pretty aggressive speeds. Then I turned the wheel hard one way and immediately turned hard the other way, as you sometimes have to do to take evasive action in traffic. It rolled real bad on the second turn of the wheel. I reconneted it. For my truck and my style driving (pretty aggressive and lots of highway miles most of the year) I want it connected. It is fine unconnedted if all is normal, but if I ever have to take evasive action at high speed, I definately want it connected.
