Long winded argument that didn't need to be made.
i've played soccer, and base my claim from experiance, it is easeir to strengthen your weak side in soccer than it is to in skiing.
you have to practice both ways, it'd be equally impossible to kick a target with your right foot as if you've never practiced with your right foot, Practice is an obvious requirement for everything you do.
what measures difficulty in soccer:
foot-eye coordination
foot placement
maybe hip location
In skiing you have to be able to
judge speed and distance calculations- (speed checking)
propper foot possition
proper hip possition
proper shoulder possition
proper arm possition
you need to judge how much jump to put in to what direction
-adjust in air if needed
what is harder to do, kick a soccer ball or ski a mountain boil it down to basics or put it to it's most extreem, you want to say it harder to hit the goal post consecutivly than it is to jump off a helicopter in Alaska... your argument dosen't really hold water
