In the first situation, where was the guy's position relative to you and the other bettors? If it was possible, I like raising here with any opponents left to act so that they are cold-calling for an extra bet (making it even less correct). Depending on the various positions, you could tip the scales between acceptable odds and incorrect odds. That said, I can see the kicker worries, but if you're cold-calling a 3 bet, you need at least as good a hand as you do to reraise (don't you?...I'd have thought so anyway).
