Amex: DBS Black ($6/mile)
Visa/Mastercard: SCB Visa(I had generous promos out of HK lately)Fubon(mainly for the draw. rarely do i get to a place that takes Vi/MC but not AMEX (either AMEX and all or none all together))
Also, I would use CX AMEX if i need the insurance. (Mistake fares, valuable electronics which i would use it pass warantee life)
