Rusty,
I felt I needed to tell you those things ( I've read) as they are indeed 'counter intuitive' - however your doing the testing, so lets see what happens.
I intend having 6 of the harder dampers. As you might imagine 6 will make it a little further out than centre, but not so far out as Tracy's. If I remember the chap testing the 4 cylinder settled on 5 dampers after testing 4 of the rubber ones. I though I'd go a step further.

 I will leave the video for a couple of days so as to not bog down your ISP. 
 
Hi George,
 
No need to wait.  I have something like 500 GB of traffic limit per month, but I don't know of any daily limit.  
 
I've spoken with a couple engineering types about this, and fully believe that what's required is a very (effectively) soft damper.  Using the Autoflight drive, there is only one bolt-on coupling that fits, and it's made by Centaflex.  This particular coupler only comes in two shore values, which are 60 and 50.  The original was a 60, and the one I got to test is a 50.   One things for sure, it will either be better, worse, or the same :-)
