i got the Huntsman today, a direct hit and another damn Big Earner. plus a scotsman's skullcutter.
i'm using the Huntsman, but the others got scrapped.
The direct hit is great for taking out sentries, or if you have excellent aim, but otherwise it's best to stick with stock. I'll admit it is my preferred primary for the soldier, but I've been using it for anti-sentry duty for so long I really fumble around with the vanilla rocket launcher.
The scotsman's skullcutter is really only worthwhile if you're a demoknight, as a shield minimizes the slower speed. If you're not a demoknight and you're using this you're just asking for a backstabbing.
The big earner is an interesting idea, but I've never used it and I don't see it on the field too often - although it's hard to tell since all of the knives (excepting the assassin's creed on) use the same backstab icon.
Also, Im calling it: Meet the Pyro this Friday!
Given the charred diary this does seem likely, and I wouldn't be surprised if it also kicks off the Saxxies.
