OK so time for an update I think after Barlines very kindly sent me a Dorco and A Feather Pro to try. Having been away this week it was perfect time to have a nice leisurely shave today, but I couldn't't decide which blade to use. Initially I thought I'd try the Feather as that's what I have been using up until today, but I was also aware that the Feather have a reputation for being very sharp and unforgiving. As this shave was all about trying without the safety net of the Pro Guards I opted for the Dorco.
So I choose my usual setup of shower, soak, Proraso pre shave and Proraso soap and started the shave. I was more aware of the blade when I started but after a couple of strokes I relaxed a bit and finished the first WTG. A quick rinse, re-lather and another WTG and then a proper rinse off followed by a cold water sploosh and then some witch hazel finished off with balm.
A check on how good it was revealed a DFS overall with BBS in 80% of places. I'm extremely impressed with the closeness of the shave and also the ease of use, which was better than I was expecting. It seems the pro-guards obviously protect you while you are learning, but do stop you getting as close as the non-guarded blades.
I shall be interested to see if there's much of a difference between the Dorco and the Feather and will try the Feather after 10 or so shaves with the Dorco, as I usually manage 15-20 shaves with the pro-guards.
