Getting this Waterballoon to not just deform but to swing naturally.

I have it where I can make the water-balloon deform (using softbody), like it would if it is moved a little but mainly resting. However what I have a hard time with is getting the Water-Balloon to swing naturally. In my blend file there is a cylinder that is supposed to be like a solid plastic straw or wooden dowel. Then the water-balloon. The dowel is in the water balloon and it is rotating. The balloon should not just jiggle but the main weight should take longer to be moved. Plus at the end it should swing back and forth tell it comes to a rest. I can get somewhat close to what I want with soft-Body simulation. Still if there is someone else out there who has used soft body more so then maybe they can help improve it.

Please download the blend file and try to get it as close as you can and then attached your version.

Any one have anything close?

Here is what I am wanting but in this I used a armature for the swing. I would prefer it if I could get not just the jiggle you see but also the swinging motion just with the soft body modifier. WaterBalloonSwingtestwitharmeture.blend (1010 KB)
