Turntable isolation platform Recommendations?


I currently have a Critical Mass isolation platform on loan. Does anyone have any other suggestions I might look at?  Possibly considering the HRS 

any feedback would be greatly appreciated..

Yes, did use Airline Arm with Vibraplane. Never had a problem. Easy going, still own the VP, the minus-k never was my cup of tea …

@syntax -thanks, noted. I remember the Kuzma Reference- had one, very easy to set up, sounded good, had a Triplanar on it at the time.
@mijostyn- I had the HRS in NY and was able to isolate the high mass table through a combination of mass loading and judicious placement of other equipment. There were some old photos of the system there I could dig out that show the table placed on a huge old Asian prayer table- we added huge chunks of sorbothane to the prayer table legs, but it was a kludge work around at best. In my NY set up, the HRS alone could not isolate footfalls and in fact, I think that some of these isolation platforms do not do that very effectively. The Minus K does.
The MinusK was purchased when I moved- to a restored Victorian house in Austin with springy wooden floors. As to adding the HRS, I didn’t like the idea of the metal turntable coupled to a metal top on the MinusK. I did speak to the owner of HRS and as I recall, he didn’t indicate any issue when I discussed using the HRS with the Minus - he did suggest I send the HRS back for a newer footer, but I didn’t bother.
You are welcome to visit if you come to Austin.
PS: on the spec of the Minus K, it takes the HRS into account and also provides me with just enough load capability to add a second arm pod (at 30 lbs). I had never ending problems trying to balance the Minus K with both arms, though. See here. Have no present plans to add the air bearing platter to the XL, but thinking about some different horns. That’s a whole other discussion! 

@tomic601 - was just listening to an old Jackie Mason routine on jews and gentiles-- hilarious. As a member of the tribe, we typically had no mechanical or other manual labor type skills- we'd call a guy. Now that I'm in the post-career phase of my life, I'm learning stuff about HVAC, plumbing and electrical around the house, but I always think about that Jackie Mason routine. He was a very funny guy-self-effacing, and got laughs by mocking his own. 
well the Brinkmann is on an HRS, cause “ I know a guy “….agree, in retirement there are more things to muck around in…. Most of the HVAC, especially the AC i leave to my expert. We trade salmon and shrimp for cold air…..
