I've found the list a very very good base/reference in my blade test purchases. It is however only a base, I didn't rate the polsivers but I just had a shave with my newly purchased Bolzano blades and think they are looking to become a fave, 2 days of rough stubble and I'm left with the smoothest face I've had for a good while, I might just put them in my top 4 given a few more goes with them.
