C/R is OK, but my personal preference is to bet out, especially if I'm trying to take down the pot right there. I want the guy to feel smart for folding. I bet out and he says, "this guy has something, maybe not something great, but it is smart for me to fold". When you C/R you can certainly take it down, but I just feel like he is saying, "I've already committed this much and I'm pretty sure I have some outs. It only cost me 1/3 the pot (or so) to see another card, I'm gonna do it!"

Just my line of thinking.
