I've always liked menthol. It's really the thing that sold me on trying a brush and real shaving cream. I used to use Edge Gel back when I used carts and didn't really like any other canned stuff but it was always so hard to find the Menthol. When I started checking into traditional wet shaving and saw all the menthol creams you could get, I was sold instantly.
An addiction? No. Insanity? Possibly! Careful or you will get a "brain freeze", like when you eat ice cream too fast!
