If I had a set on that board it is unlikely I would raise on the flop. That board is about as perfect as possible assuming the original raiser has a big ace. Even that turn card is not scary for someone with 88 or TT. Sure there are straight draws out there but I may well wait until the river to pounce.
With 2 pair it is possible I would raise or lead into the original raiser or wait until the turn.
