I don't really know what to make of these posts but I find them fascinating!
Do you have a Wilkinson Sword blade to photograph? If not I'd happily post you a pack - they're one of my favourites and I'd be interested to see how they shape up.
I love my GSB and Black blades. I'm still deciding which is my preferred blade to use, but I love that I don't have to decide which one is better. I can switch them out in rotation and smile no matter which my razor is loaded with. The best part is all of my razors seem to get along with those two blades. No issues at all thus far! :-D
