i like the raise here.
two things. If he has an overpair (hence preflop reraise) he now has to be a least contemplate you had a pp or suited connectors that have hit this flop (unless you dont play them like this of course)
second the reraise may and only may make him reraise you back or push telling you where you stand.
I guess the reraise on the flop is buying you information but also you are taking the position of aggressor from opp. Thats why id reraise anyway and why i like it
