I have a Goodfella stainless steel OC razor head (Goodfella razors are manufactured in New Zealand) that I use on a Griest handle. It is so mild it makes a Feather AS-D2 feel like a Muhle 2011 R41. We are talking *extremely* mild. It works great with really sharp blades like Feather, and I've also enjoyed Treet carbon blades in this razor, as well as 7 O'Clock Yellow blades.
The "Goodfella" name is from New Zealand slang, not Brooklyn wiseguys....
