Good info. I wonder where the aluminum Lupo fits in there? I only have the GC 68-P but it’s a nice piece
I have the Razorock Game changer .84 also, it is a little milder IMO. If you want to bring the RR GC .84 up a notch I use the Kai SS blade which is a little wider blade than a standard Gillette blade and it makes the razor much better for my feel & results but leaves the GC .84 still a carefree shave. The RR GC .84 is a great razor and well built. The Lupo.72 is a better built razor for installing and withdrawing blades, has lather channels for a safety bar that to me is important. It is just a nice carefree shave with the razor and results are little better than the GC.84. If you like blade feel folks really like the Lupo.95. There is not a lot of difference in final results between the Lupo .72 or .95 from my understanding.
