My first safety razor was the Gamechanger 84P which is amazing. I got curious and bought the Lupo 58, 72 and 95 and the Lupo 58 and 95 are keepers, the 72 causes some irritation. Also have the Gamechanger 84OC and find it no better than the Gamechange 84P so will probably sell that at some point along with the Lupo 72.
I REALLY would love if RazoRock released a Gamechanger 100.
You could put one shim between the blade and the plate on your Gamechanger 84P and that would make it about a 94 or two shims would make it a 104.
I also have the Gamechanger 84P and the Lupo 72 and 95. So far I haven't really gotten that excited over them. I mean I love the high quality and fit/finish and the price - that's pretty much hard to beat - but I almost always reach for a different razor. I bet if I spent some time with them I would learn to love them. But I generally reach for either my R41 or my 'merica and find that I can get a closer shave with fewer passes.
