A SR?Anything that has a slim and also very rigged head design, preferably with a very steep angle, polished or plated (no matt finishes or unpolished and non plated bare brass, bronze or copper) and smooth bar plate or open comb teeth. I also have other minor requirements, but if a razors fits these, then the chances of me liking the razor are pretty good.
Razors that kinda fits into those requirements are:
NEW LC/RFB/NEW FB - I'm putting them as one razor, since there isn't a huge difference between them
New Improved
#160 Goodwill
Razorock Game Changer .84p
Razorock Lupo DC (with both .95 sb and .72 oc) - it's not a bad razor, but the bar isn't very comfortable and I don't use that razor very often
Barbaros TR2 and TR3
Blackland Blackbird - it fits the requirements to some degree, but not entirely
Gibbs #15 - same as the Blackbird
