1/2 NL Harrahs

I raised to $17 UTG and got 4 callers. The table was pretty loose. The pot is around 70 - the rake.

Flop comes

The two spades scared me and I went all in for $67. Did I bet too big? I figured no one could chase their Ace or flush draw with this bet. But mabye I could have gotten a caller if I bet around half the pot. But then I wouldnt have enough money left to push them off their draw on the turn.
