I don't think rails are bad for skiing, but at teh same time, i feel, like many others do, that skiers should be more competent at a variety of skills. Being good at just rails or just jumps or just moguls does not make you a good skier. someone who can rip a bigmountin line in the morning, kill it in teh park after lunch and hold their own anywhere on piste (groomers to glades etc...)before the end of the day is a good skier
