I've had several Progress razors, including one Mergress, for years now. I used them a bit when I first got them but then fell down the rabbit hole of high-end stainless and titanium 3-piece razors. A few weeks ago I wanted to give the Progress a spin again. I also wanted to try a blade I had not used very much, and not for several years....the Astra SP. After loading an Astra SP I left the razor at its lowest setting and proceeded to get an amazing shave. Plenty of efficency without a hint of issues, no micro weepers, no irritation, just a great, smooth shave. It was such a great shave in fact, I've used nothing else for the past several weeks. I only use each blade 2 or 3 times then pitch, typically along with either DR Harris or Haslinger lather and Speick AS. This oldie but goodie was a sleeper combo sailing right under my radar, now rediscovered and enjoyed immensely. Enjoy your day!
