first week impression - ranked in order of comfort (totally subjective of course)
1) Rapira Swedish Supersteel
2) Gillette Silver Blue
3) Persona Med Prep
4) Polsilver SI
5) Gillette 7o'clock Black
6) Rotbart Extra Thin
7) Astra SP (pulled and inefficient)
I felt the same way with the Astra. My favorite so far has been with the Personna Reds. Very comfortable shave.
