Anyone else ? The Bolzano blades provide aural feedback like no other ! And instead of hi pitch screaming whiskers I get grumbling and deep hairy death cries. Granted I am comparing to no more than merkur/derby/lord/feather/astra ... but there is a real difference. They also provide more tactile feedback but without being "grippy."
I still love the feathers, esp. in mild razors like the barber pole and the Muhle. I think I have now chosen my two blades for mass purchase; feathers and bolzanos. I admit, I also love their individual paper packaging, little luxury.
