Just got my 3x CLI from AMEX couple days ago. Total util was about 5% across all cards but 18% w/ Amex. Basically two cards with balance and three w/o. With that said, Not sure what it was when they softed me but that's close. Not true that you need to be at 0 bal with them at time of request. I went from 3500 to 10000.
