I am looking at the three sets of shallow sockets. Proto, Koken regular not Zeal series, and Williams usa. Does anyone own all three brands and if so can you throw up some photos comparing each? Have any measurements such as height, widths of sock and wall thickness of each? As for the three brands which do you think had good tolerances and strength. I heard the williams usa can split pretty easily. Proto is a big chunky, and Koken might not be as strong and wear faster. Any thoughts?
