Lower International is a little more mellower than the upper section.
There are still a couple steep pitches, but they are separated by flat benches where you can catch you breath.
You can get on Lower International by skiing Upper International from the Silver Queen or Ruby Road, or you can get on the Yellow Brick Road that crosses Keystone, Jokerville, Twister, and Crystal before it hits International.
As you descend the rolling pitches, stay right past Championship and you'll hit a long flat before the last steep towards Warming House Hill.
You'll merge with Lower Twister and be able to access all of the base area lifts and amenities.
