Any successful Thai is almost always at least a decent kicker. Even the clinchers that don't kick much are capable if they chose to fight that way. IIRC Petboonchu pretty much got the better of Jomthong outside the clinch the first time they fought years back. Yodwicha used to kick more when coming up and was alright.
Maybe I haven't seen enough of him, but Pornsanae doesn't really seem to be a skilled kicker to me. He throws hard kicks and a lot of them, but I haven't seen many setups from him. If anyone has better info feel free to correct me.
