Actually it is you Tbg who is clueless and in denial. If you read the article through you would understand he goes into both sides of the issue positive and negative. That he explains why how and when they are useful and the theories behind them. He explains why the floor disc need to be small and how they effect the spikes. If you do not like this article there are plenty of others out there. Do a little research, google it. You are buying into bull and don't know what to do. There are only a few co's out there that really understand or take the time to design proper well thought out isolation products, SAR, HRS, Stillpoints and a few others. You convince yourself you can get as good if not the best at very low pricing. That it cost nothing to properly design something let alone manufacture it. Then call an article delusional or poorly written or as if it was written in the 70's, like isolation facts have changed since then. Simply because they point out in an article how little you obviously know or understand. Burn the writer at the stake he is spreading unclean thoughts that I do not agree with or fit into my world! Like I said, "you guys are funny".
