I would also say to call the flop and lead the turn. I usually never slowplay any hands unless I'm sure that my opponent will bet into me when checked to. 3-betting the flop would most like chase away hands you want to keep in the hand i.e. TP, JJ, QQ, AK or AA because they will not fold unless you show too much strength.

I like that you led the flop with a weak bet which disguised your strength.
