Get some higher speed film, and a neutral density filter so you can really monitor your shot correctly, and still use a lower Fstop, if you're going to do it.
really, shooting skiing with film is pretty cool I think and yields some interesting results. I don't get the whole 'you can't shoot sports with film' stigma that a lot of people have developed these days. I mean, shit. People did it for YEARS guys. If it's a little blurry? who cares... you shot it on fucking FILM and the process makes it sweet!
First 35mm roll I ever shot of film was back when I was probably 12 years old, and I pumped a roll of 36 black and white frames through my mom's Olympus XA2. My focus was a bunch of friends going off dirt jumps on bikes and skateboarding and shit.
A few of them were blurry, but everything was fast enough to give real sharp images for the most part. I cherish those shots to this day.
