oh, man... I'm not good at this... but:
first set isn't too big. right jump and left are about the same. 20 feet?
second set, maybe 25 and 30?
and then 35 and 40.
Again, take this with a grain of salt. The thing is, they aren't long gaps, but they're steep landings and pretty steep lips. It's just a lot of snow and it's really intimidating. Idk.
