mistake to raise this pot?

Just played this hand, and wondering if my postflop raise was a bad idea given the monster hand I had. I pulled the trigger here thinking I had tons of pot equity at this point and could catch each player for another small bet. Could I have made more by smooth calling and reraising another BIG bet on the turn? Please comment.....
