suspension vs non-suspension design

Hi, what is your opinion regarding the issue of suspended vs non-suspended turntable designs. Do turntables with suspension have more PRaT in comparison with non suspended tt's? In general the current trend in tt design is non suspended, high mass. Is this because (and I hope I do not insult any tt designer) it is more easy to design a non suspended high mass turntable than a suspended one? I can imagine that for a DIY tt it is more awkward to built a good sounding suspension tt, because of the complexity of the different parts of the suspension itself, the difficult mathematics regarding stiffness, damping qualities, configuration and mass of the suspension, etc.

I think the issue of PRaT has far more to do with mass/energy storage than suspended or non-suspended. The Xerxes X/20 and Avid Volvere and Volvere Sequel are among the benchmark tables for PRaT and they are suspended. The non-suspended Regas and the Empire 208 also have good PRaT.
Many of the behemoth American tables have very poor PRaT.
