I stopped doing daily rotation because I wasn't consistently getting good shaves. Sometimes I'd find a combination gentler than expected and do a lot of chasing and wind up with irritation - or I'd find a combination more aggressive than expected and wind up with nicks. So, for the last several months I've been doing one razor, one blade, and using that setup through the life of the blade. As a result, I'm getting better shaves and getting a better feel for each setup and how to finesse a good shave out of it. YMMV, but that's how I've been doing it for a while now.
Currently I'm using a 50's super-speed and a Voskhod.
I use 2 razors each shave: a mild one first and a more open blade on second.
Feather AC/DC and Karve open comb A both with Wilkinson Sword Light Brigade.
Game Changer .68 and Game Changer 84.
Gillette Tech and 47 Aristocrat with the original Polsilvers.
I try to use a razor for one week. As of late I have been using a Ball End Tech exclusively, It is my best shaver in my book. I did pick up a few additions this week, A Super Speed blue tip A-3 to replace the one I had PIFed.
40's Super Speed Z-4.
Black Handle Super Speed M-1.
Black Tip Super Speed W-1.
