Well I don't understand why Head doesn't make a top notch slalom ski. What's the big deal? Stockli can do it.
The Wcup stats are somewhat irrelevant as they're one offs. But apparently even there they don't make great ones? Don't know.
Ligety can't switch himself from his gs technique of hurling himself down the mountain and ending up near the tips of the skis as they come around. From that to slalom seems to be too much right now. Not that he's terrible, just not at the very top.
