I've had the GC .68, which was too mild. I've also had the Hawk v1 in chrome, which shaved well, but the chrome started lifted and IB were not interested. Kinda put me off. But I am very interested in the stainless Hawk OC.
And I think I am tempted by the Gamchanger Jaws or .84 OC...
And the Lupo looks cool...
