i thought about it for a while then kicked the idea around some more.......i still like the idea of a 7 day set but your still just using the same thing every day i would end up using monday every day until it needed to be honed then start using tuesday to the same effect.
but on the other hand a cased pair is more practical and cheaper... perfect for a weekend trip you dont have to bring a strop with you, the razors are in a protective case(one less thign to worry about) just a brush a bowl and some shaving cream

but it all comes down to what YOU want do you want to use the same thing everyday or would you rather use something different every day?
