Fun with limitations
Super fun and awesome alternative to lugging a huge drop in around. You need a crew to hit things though as it is really really hard and exhausting to pull it back by yourself and launch, pretty much impossible on a snowboard. Ideal - one person dropping, 2 people pulling it back, one person on the camera. They are heavier and clunkier than the description lets on, you'd need one hell of a pocket to fit this in there.
It is a really nice controlled pull, its not a strong jerk at the beginning, it gradually pulls and increases speed.
