I've been using MWF with a Chubby 1 since Christmas. I can't believe how little product is needed for a 3 to 4 pass shave! I'll have that puck forever!
I think that you may find that the best way to find out what you like is to try out different soaps. You might notice that we all have differing opinions of what is "best".....thus YMMV. I am still in the early stages of this disease myself, so I'm still learning. Of course if you spend the time to research the different soaps you'll notice certain ones keep having good things said about them.
