I used two...Timeless SS scalloped .95 on the left side, ATT SS Windsor H on the right, with an Astra SP. Received both razors today, so this was their maiden voyage (I‘ve been using an ATT classic H since spring 2017). The last time I shaved was Saturday. Soap was Mike’s Barber Shop, brush was my SB Chubby 2. I did one WTG pass and was blown away by the smoothness of shave from both razors. Decided to stop there (I normally do two and a touch up). Anyway, a remarkable shave for one pass - two little stings with the alum (finished off with Fine Italian Citrus). Going to be tough to decide which razor is better for me. Should be a fun process.
