The slice credit card, although doesnt have very high reward rate, is still good for getting cashbacks below Rs.100 purchases. The slice in 3 feature can be handy for big purchases. I m personally waiting for the "spark" feature which is comming soon. It gave huge discounts on brands during their old slice card days. Since it is LTF there is no harm in getting this card.(only concern in ur case could be that because u already have 6 cards and no SBI card yet, try to get that SBI card asap before u become overleveraged).
