Just a note, I do understand being more worried about them calling your all in in a tourney, and especially rather deep into a MTT (and extremely especially if you're nearing a big pay increase, or just about to enter the money).

Although in those cases, I think the all in on the flop is more likely to scare them out than a pot size bet.

But in any case, the risk is greater there, especially if you're going up against a bigger stack.

In a ring game, it just doesn't make sense, as long as you aren't playing in a limit that your bankroll can't support. Being the huge favorite to double your stack (if you're up against an equal sized stack), you should want to get all of both of your chips into the pot. If you lose it, sure it sucks, but you'll win it 3 out of 4 times, and it shouldn't be the end of the world if you lose your stack either, as long as you're playing within your bankroll.
