We can probably get by with only one outfit of clothes or only one hat, but that is not much fun. I have a go-to DOVO that I use almost everyday while occasionally rotating with one of my others. It is fun to experiment. I try and learn new things everytime I bust up my shaving routine with a suggestion from this forum or with a different DE or SR. This hobby of wet shaving is a fascinating journey with no destination punctuated with perfect shaves. Enjoy your trip. :)
