One advantage that many people overlook with large blades is that you don't need to rinse off nearly as much as with smaller blades. I enjoy shaving with a giant Filarmonica and being able to shave an entire side of my face and neck before having to rinse. I like how a large blade holds so much soap. Dropping down to a smaller blade can seem kind of a let down when you are rinsing all the time. To that end, I think a larger blade can save a little time on the shave.
