I've had the misfortune of meeting the head Pony Carbs guy. I have no idea how they stay in business if the head man has an attitude like that...if you ask him, they are incapable of making mistakes. Plus, their official recommendation is to tune by ear, and that's a good way to cover up any carb problems you might have.
I haven't used one of their carbs (and I never intend to do so) but I've heard quite a few reports that they don't do nearly as good a job as they claim. They are the best out there for "LOOKS" but I've heard horror stories and seen some awful evidence as to how good PC is with the mechanical side of things....like how thorough they are when it comes to cleaning the blast media out of the inside.
