Using less efficient, more expensive blades to make a razor less efficient certainly dulls it "wow" factor.
You can use it with Prolines, but your technique had better be spot on. It's not much of a "safety razor" with Prolines. Overkill for me.
Also Feather Pro and Feather Pro Super are affordable on Amazon these days.
Prolines cost me $.37 a blade, anything more than that is expensive.
It was the hunt for daily BBS that moved me from cartridge to safety razors. If I waited every third day, the supermarket rebranded Dorco 6 and hand-lathered Irish Spring would do it all fine.
I use to shave daily. With the SE1/Proline, BBS last for at least 20 hours before I feel stubble break skin. So there's nothing really to shave on day 2.
BBS with a Gillette Tech only lasts for 3-4 hours before stubble breaks skin.
