I am truly sad. I used up my very last SI blade. I had been holding on to it for quite some time and I finally decided to use it. I used for about 5 shaves too. typically blades only last 2 - 4, and my SI blades last for 4 good shaves.
So I am in my search to find the next best or closest blade to the SI.
I have used:
Gillette Black, Yellow, Green and the Super Thins
Astra (which are not that bad actually)
So I am looking for a consensus here as to which blades are the closest to the SI's
