White Amex-
I think to get a pre approval, one either has to be a prievite banking client at the issuing bank, or have a large credit line and good payment record with the issuing bank. They try to target big spenders, so if you charge as much on a Visa as you do an your Amex you would be the perfect candidate for the Visa Infinite.
I still think that the Centurion Card is the
best
