I got your Mamba when it first came out and it was the smoothest and most efficient razor I owned. When the Game Changer came out, I immediately got one. I had high hopes for it, but it disappointed me because it was a rougher shave than the Mamba and not as efficient. When the Mamba 70 came out, I did not see how the Mamba shave could improve, but I was proven wrong as it was just as smooth but more efficient than the original. When the GC 84 came out, I hesitated for a long time thinking that if the original had a rougher shave than the Mamba, a more aggressive version would be worse. It took me until now to finally break down and get one. I shaved with it tonight and was again proven wrong. The bigger blade gap actually made the shaving more efficient and so it was not as rough as the original GC and I got a closer shave with less passes. Tomorrow night I am bringing out my Mamba 70 for a shave off.
