Topwater Lures??>?

[hazmattr]

I am sold on top waters after yesterdays audience for em. The problem is I didn't set the hook on one of them. I have always be skeptical about them but man they are pay day. I'm wondering from you more experienced fellas on when to set the hook. I kept a eagle eye on the lure every time and could see the fish seconds prior to the strike. Which makes me think I set the hook too soon, I'm not sure. When getting a strike on topwater do you wait to feel a tug. Or should you know when to set. Using swim baits which i'm use to, I obviously wait for the tug. I'm new to topwater so advice would be appreciated.
