If a person is regearing, it is my personal opinion they should go with a full carrier something such as a selectable, Truetrac, Powr lok, Detroit etc.

what you were experiencing in your Cj-7 was the lack of lateral stability because all 4 tires were slipping at the same time. With an open diff, when this occurs, the tires not spinning stabilize the jeep. That's what makes selectables that are open when off and spooled when on versatile. Ice, especially black ice, can screw with detroits more than an ls be their unpredictability as well. Remember, there is a difference in driving on snow and ice!
