Good morning guys. Yes the Astra SP didn't work out so well for me when I first started DE wetshaving about 6 months ago. But now, the Astra SP works awesome! Just like many other blades I've loaded into my vintage Souplex OC. I'm convinced it's all in the technique, no matter the brand of blade. Bad technique, bad shave. Good technique, good shave. And I've loaded several brands of blade into that razor over the last couple of months. Astra SP, American made Personna, Lord Platinum Class, SuperMax Titanium, Rapira Platinum Lux, Feather, Gillette Silver Blue, Gillette 7 o'clock yellow, all gave great shaves when the technique was right. Astra SP is just another great blade amongst many. And that old Souplex is now my daily shaver.
