* safety (especially large unforeseen sudden moves)...and hence peace of mind. you thereafter never trade with "scared money".
* more leverage of capital
* adverse movement is lesser than the pro-movement for the same movement of spot.
* more effective stop loss.
* lot of flexibility viz. a viz. which option to buy
* deeper in-the-money options have much less premium and move as much as futures.
* options have inbuilt stoploss.
all i have to guard against is the time decay.
