yeah it sounds good, i agree you might want to upgrade to discs, if snow gets in your v brakes they might stop a little less than nothing
in my winters here in the NW discs would be nice too, but im cheap so i just pay close attention to how my brakes feel, and when they start to feel weak i stop and clean the mud/snow out of them. when they're just wet though they still stop pretty well. you could just ride it as it is and upgrade to discs if you find you are needing them.
