I have a current rotation of 2 half hollows; a quarter hollow and 7 full hollows (2 singing). They vary in width from 4/8ths to 13/16ths. Almost half are round tips.
I get a different shaving experience every day and I look forward to that difference.
Seriphim's recent thread "A Hollow Apology" got me thinking about what you guys think about using a bunch of different razor type as opposed to one standard style even if that type is your favorite.
