I was going to also comment on the Double Tap but never found the time to this morning. Anyhow, I think Double Tap, like said, is mainly a waste. Even if you use Double Tap on a gun like the M4, it is useless. Sure, it's a faster firing rate, but you waste more bullets. It is much better to use Stopping Power. You could definitely argue that Stopping Power and Double Tap are the same, but I think Stopping Power has much more of an advantage. For one, you have to watch your magazine. Of course, with a gun like the Skorpion, it's no

ing brainer you aren't going to use Double Tap. Using Stopping Power, Your clip will last like 5-6 seconds held down. With Double Tap, who knows how long it would last -- maybe 3-4 seconds? You'd spend more time reloading then you would shooting.
Keep in mind, that not all the time you'll see an enemy close to you. I will guarantee that you won't be spraying long-range. This is where Stopping Power comes handy. Stopping Power is indeed great with long-range too.
In essence, Double Tap is a good perk if you need it as like a beginner, but there are other perks which are much better than that. The only time I would think Double Tap would come into play is a Shotgun. I haven't tried it myself, but if you're using a shotgun, if you miss your first shot in close combat, you'll probably be dead. Double Tap might be able to speed up that time-delay inbetween shots.
