Used 2 today, An Astra SP at 3 days in my 6C on plate 5 for my first WTG pass (3 days of growth) and a Derby Premium in one of the plastic WS razors on it's first shave. Worked well for the first time using one of those plastic WS razors.
PPI red box Gillette Stainless (4)
I was worn down and cranky this morning and not in the mood to put any effort into shaving. But it gave me a really good one anyway.
