Action Sports Cartel

I always have trouble deciding what to take, and what to leave at home when I go on a trip.
This is what I'm working with:

I am going to Sunday River in Maine, and will be shooting in the park; jumps and rails. I will be shooting mostly during the day and possibly at night.

So far I have packed:

D300
D70s
10.5mm
60mm macro
70-200 2.8

2x Lumedyne 065 Pack
2x lumedyne batteries
2 Nikon sb speedlights

4x PW+II's

Sekonic L-358 (Will I actually use this or should I just do it a la Dan Carr and do it by eye/histogram?)

4 lightstands.
Cords and brackets ETC.

Currently I have my body separated from any lens, which means I will be setting up the body with lens on the mountain. Would you guy's advise against this, because of getting snow in the cameras?

Thanks!

don't worry about the camera being separated from the lens part too much.. when you're switching lenses just make sure you've found a nice quiet spot where people won't bump into you or throw snow in your direction. If it's snowing or raining just be extra cautious and cover stuff with your body/bag.

got photos from your trip?
