The thing is CIMB DA is truly Free For Life and great as standby card, don't have to worry about swiping x number of times or go thru the hassle to call CS to get annual fee waived. Don't spend a single sen also no issue.

Noted you want Cash Back card, besides the cards you have, the other Cash Back cards don't really benefit you since you don't need it for petrol and the only other card that I can think of which is better than OCBC TMC is Alliance Plat (for non petrol, groceries, utilities and telcos). The Alliance Plat earns you minimum 1% equivalent cash back after taking into consideration of the points but Alliance got not much promotion except that the Plat grants you unlimited entry to KLIA PPL. But like most cards, the annual fee is waived with 12 swipes.

So, the only thing I can think of is look for a card that gives you like 10% discount at merchants you do patronize. You will need to spend time checking out the banks websites yourself    For starters, click here to check out Citibank Credit Card Promotions.
