Townshend platforms vs SRA platforms

So, am I to understand that the Townshend platforms use some kind of spring? Think this refers to my op. Or are the Townshends actually more on the solid side? BTW-the SRA Ohio Class platforms considerably more than the Tp.
Then we have the perennial issue of price vs quality.
Another thread?

Nah man adapt, roll with it. https://youtu.be/y6NxWID2r6E?t=33 

Townshend are modular. Podiums, Bars, and Platforms are all based on the same fundamental technology as Pods. They all use an air valve damped spring. Pods the air damped spring has a top that turns for level adjustment. Bars and Platforms are basically Pods attached to a bar or a platform. Podiums use a more sophisticated platform as well as Pods at each corner that are more adjustable, with adjustments both top and bottom. 

With Townshend the technology is all out in the open. You can unscrew and handle, see and understand what is going on. SRA is the epitome of Buckminster Fuller's "the ephemeralization of technology". The technology in that case is all inextricably built into the materials inside. 

Wow I didn't know that SRA is much better however.
