What do you normally ride your DIN at? From what you've given us, I'd say get a binding with a max DIN setting no lower than 14, however, you could probably go with a 16 DIN or possibly even an 18 DIN binding depending on what you normally ride at and how comfortable you feel with them. That being said, my recommendations for what I would ride if I were you (I'm not saying this is what you should ride, because I'm not you, and honestly only you can make that call), FKS 180 would be my top pick, STH 16 would be 2nd on the list, followed by FKS 140 and STH 14 Driver, followed by Tyrolia Peak 18s, Marker Jesters, and Peak 15s. I honestly wouldn't touch a PX 12 at your height/weight, you'll probably destroy them.
