As other members have pointed out, it is useful to be able to do both shuffles well. Since the Hindu shuffle seems to come more natural to you, I see nothing wrong with using it the majority of the time. Spectators notice when we handle the cards naturally (and vice versa) and when we handle the cards smoothly and naturally, we are less likely to arouse suspicion. Both the Hindu Shuffle Force and the Hindu Shuffle Control are highly useful moves and can be very deceptive when executed cleanly. If the spectators see you using a Hindu Shuffle just as your ordinary shuffle, they are essentially being trained to accept it as normal and natural for you. Then later, when you use the Hindu Shuffle as a force or as a control, nothing will look out of the ordinary and you will be able to accomplish a force or control quite deceptively, and without arousing suspicion, when you need them for a trick- which is the goal. Enjoy!
