Me? Have an opinion on ring circuits? I wonder what gave anybody that idea!
The problem is that the OCPD needs to be limited to around 20A to afford proper protection for the tools/cords connected to the outlets. So if you have the same number of outlets in the same positions on a 20A ring or a 20A radial, you'll still have the same potential problems with overload and tripping.
The only real way to reduce this as I see it is to increase the number of circuits and lay them out to minimize the chances of heavy loads being on outlets on the same branch simultaneously.
