I am now primarily going to use my starwood amex card and my MBNA worldpoints when a place won't take amex but was wondering since blue is such a difficult card to get, from what I have heard, if I should keep it for this reason (may be a good sign to future lenders, I don't know?), instead of reallocating my entire blue CL to my starwood, and thus closing blue, since starwood will now be my primary use card?
