Hey, Im new to the whole snowboarding thing. i've been shooting for almost a year now and i mostly shoot BMX. But i was wondering if you can all give me some tips on what to and what not to do.. I have a canon 30d with a 70-200mm 2.8L and a tokina 10-17 3.5 and of course the 18-55 kit lens. Will the telephoto and the 10-17 work good for boarding? idk if boarding is like bmx, but with bmx i use my fish eye 99% of the time.. I also have 2 pocket wizards with a vivitar 285HV flash. Is a fill flash needed for snowboarding photography? Im going on like a 6 day trip to vermont and want to get some real nice pics to bring back.

Thanks
