I know YMMV, but Voskhod were okay for me in my Progress, but my best shaves so far with it have been with Ascos. Odd but true. They might be my favorite blade so far, beating Personna reds, and it's a toss up between them and Astra SPs, at least in the Progress. I have to try my 7 O'clock greens in it next.Merkur Progress (2.5) / Voskhod #8.
