I bought a 100 Supermax Stainless as it pushed my buy into free postage country - so they were free in mind (ahem).
I've used a blade in each of my razors (Fatip, Muhle R41 and EJ DE86) and in the Fatip and R41 I had exceptional shaves but did notice the 2nd shave was a bit rougher but still ok and again very close. not sure I would have gone for a 3rd though
