I was hoping people would be willing to share their AC blade experience. I've tried only 3, including the Schick Proline, the Feather Pro and the Pro Super. I haven't yet found a Feather blade, DE or AC that I can get along with, so for now I'm sticking with the Proline. I've ordered some Kai pink since they seem to get some love around here. I've never tried a guarded blade, but I don't think they'd fit my Paradigm razor. That's the extent of my knowledge on AC blades.
