ISA is enough in my opinion if you opting for practice. CS is almost eqivalent to CA and practising CAs can do 70 to 80% of the work which is being done by CS. So in my opinion, there is better scope for ISA courses (From India and Out of country) in practise, then CS. CFA is better option if you choose for job, or you are planning to grab some BPO/KPO type works in future.
