C-bet sizing

[VegasRunner]

I was wondering if anyone had any thoughts on how big to make a standard c-bet because in my mind, it can seem a little arbitary at time. Generally speaking, the larger the c-bet, the more is being put at risk, but the more likely the villian is to fold.

My c-bet might grow depending on the opponent, my normal c-bet is about 60% of the pot. 60% seems to be enough to make a decent villian fold if he has completely missed the flop, but in my experience, anything smaller seems too look like weakness and is likely to get check-raised by a bluff.

I like 60% because when I do have TPTK or better and it's a value bet, it's small enough that most people will incorrectly draw at their hands hoping that I'm going to justify their draw with a call if they turn the visible draw.

I realize that this c-bet is probably smaller than most people's. I'm fine with that, but I'd like to hear some other thoughts--particularly from people who disagrees with me.

(Please don't respond only by saying that a c-bet is dependent on the villian's tightness or aggressiveness. I think most of us know that the best c-bet is the smallest that gets the job done the highest percentage of the time and I realize that it's going to change based on your read of the villian. I'm more interested in replies taking a general stance rather than giving a response about how incomplete my question is.)
