Joining the party with my Feather SR. so far I have had 7 partial shaves with a Feather Light blade. Still feels very awkward, but it is improving. Cheeks and neck are going fine, with the grain. Chin and upper lip are still done with a safety razor. It certainly is a lot of fun, but I am still far from being as comfortable with the Feather as with any of my safety razors.
I will give the Light blade a few more turns before switching to either a guarde Kai or a Schick proline P, but probably the Kai first.
On the upper lip and chin I find the razor very rough, but that probably is 90% user error and perhaps the Light blade. I will master the big areas and downward strokes with right and left hands first, before venturing in more difficult areas
This also made me realise even more what a joy and easy to use razor any of my DEs or ATT SE really are, to be able to whack it around my face without any worries!
