I hunted with mine this year in sunshine, rain, snow, and below 0 temps and never had a problem with any of the whiskers freezing. I haven't used the no snow ( I think that's what it's called) yet but I guess it couldn't hurt. As far as the whisper disk, I've heard stories about clearance problems (could be due to improper tuning though). I love my biscuit and wouldn't trade it for a fall away ever.
