Currently have 4 open platinum cards with last one in August, total of 9 platinums in my 24 month history. 42k combined credit limit with Citi includes Hilton, 2x cash, costco, 812 fico. Last platinum came with a $14k credit limit. Sitting on a 65k mailer right now with a January expiration ate (not sure if they really enforce those) wondering if I should

1. close one or two of the current platinum cards (oldest will be a year in December)
2. reduce credit limit across all of them
3. just go ahead and make the application and agree to reallocate credit (would prefer to avoid explaining why I need a 5th platinum)
