Yeah, there's no way you're getting away from top set there when you've got a LAG image and there's a potential flush draw on board (although you seem to doubt that it could be a semi-bluff minraise anyways).

I guess the only thing I could say is that your preflop raise is small considering that you had 5 callers already. That means there's already $3 in the pot. So if you're going to raise here then you should raise the whole pot size, up to $3.50. You also want to reduce the number of callers ideally when you're playing a tough hand like 99 out of position. The problem is that with your LAG image your raise might not get enough respect and limit the field like you want it to. But it would have reduced the implied odds for hands like 78.

Alternatively you could just call preflop and play it for the set value (my default play), in which case you would have gone broke here anyways.
