I've been wet shaving since I grew a beard, so roughly 25 years, give or take. DE shaving six years. But now I feel those initial DE years were random ramblings. I was jumping from one razor to another without considering or focusing on other parts of the wet shaving process, such as technique, lathering, and blades. Blades made a massive difference when I started evaluating different blades few months ago and how they behaved in different razors. My favourite blade is BIC, too—Nacet in mild razors like DE89. So if I would try Rocca today, I would most probably use BIC in it. Today I shaved with R41 again. First pass with R41+Minora. Second pass 6S Plate 6 + Astra. I feel 6S is one of those razors that work well with almost any blade, although now I consider Astra P as meh blades. They are leftovers from my previous purchase.
