Pleased to be corrected.
I'll amend my initial statement to my suspicion being the Gillette Super Blue that Nolisco & Blademonkey tried and the description of that particular blade seemed similar to the Tian Li SB I tried, which I believe was the same blade as the Baili Super Blue I tried as well.
With the China market being flooded with counterfeit goods, fakes of the Gillette Super Blue being sold seems a very likely occurrence.
Your experience of the Gillette Super Blue seems to lie close to another MIC blade I have used, the Rimei Platinum - which is one of my favourite blades. There seem to be a number of different MIC blades which I think all come from the same Shanghai factory and the blades they produce seem to fit into a couple of categories of either superb or awful - little in between.
