ok definitely do not get the xl2 unless you have that much money to blow, cuz it sure is an awesome camera but for skiing you dont need that big of a camera, cuz its too big and since its 4000 dollars you wouldnt want to risk anything happening to it on the slopes. if you are looking for an excellent camera that is easy to use and lightweight i would definitely go with the vx2100 everyone loves it who uses it and its way better than the gl2. if you really want to learn about cameras to use go to
www.skateperception.com then click on reviews and there you go. i know its a skating site but skate filming is so much more advanced than skiing just cuz its been around for so much longer. anyway sorry about the length but the sony vx2100 is surely the right choice.
