every single one gets paid off each month (despite the ridiculous amount of $ I put through each card ), there are like two things I don't pay with a card and one is the maid's wage (if she starts taking cc's.......that one would be on the card)
me and wife travel a lot and its hard to do that without cards
I would downsize to two but I am sure that if I wanted to get it back later on....it would not be that easy in this enviroment (actually I just asked the bank to lower one of my limits by 6k which they did in less than 24 hours LOL)
