Only soap. I have one soap in a mug in the bathroom. I have 2 creams and about 12 soaps in a box in the closet. As soon as I found a soap that worked well I quit looking. Most of the soaps in the closet are different flavors of the brand I use daily — bay rum, lemongrass, ginger lime, lime verbena, etc. I'll use them one at a time as the one in my mug runs out. A puck lasts me about a month. I don't "rotate" anything connected with shaving using one razor, one brand of blade, one brush and one soap for weeks or months at a time. Richard
