keep in mind that you don't need to be shooting in sequence although it can give a cool effect...im fine with my 3 fps and i think yours is the same. i actually found that the lighting with snow allows for a much faster and crisper shot than when i usually have to shoot indoors at some sports event and i have to pump up the iso. With the snow bouncing the light off the snow soo much it allows you to have a much lower iso.
