Yeah, it's a requirement for doing solo. Not necessarily to be good at them, but to know what to do. When the wind is strong enough, we also train them all the way to the ground (at the home base, where the grass surface is known to be flat enough). If you do them right, you'll end up landing softly with no forward speed, but as long as you land with say, less than 10-15mph forward speed, it will still feel very gentle.
