Im leading this one for sure, a lot of times people will just see it as a c-bet and i highly doubt he is going to put you on a made flush. If a fourth of your suit hits i would slow down and see if i can get him to make a stab at it. Honostly though i feel like a lot of time here you arent going to get much action unless he has another high flush draw, and depending on your opponent a set.
