MOTO S4 Steel is the way to go!
The Moto is the best head razor available, and the steel is the way to go! The weight of the razor feels good, it lasts longer than the regular, and totally worth the extra price. I’ve been an head blade user since 2000ish and own 6 steel Motos - one in each shower, one in my travel kit, and a few spares just in case. I’ve only had to replace 1 steel Moto in all that time. I have also the original Greenblade I’ll never use but instead as a souvenir and tribute Todd.
