Actually I am going to crank my Slim up to 7 in tonight's shave. It's the first time I have set it that high. Probably pair it with The Israeli P on it's 22nd outing. I have 3 blades in rotation at the moment. A Crystal (3) and a GWS S/S Indian (5). Unsure what blade to use here..
Perfect pairing!
It's a coarse 3 day+ growth. How does it perform on that setting and growth? I'm still experimenting with my Slim.
