The Crail Slide is a type of Tailslide with a stylish grab.
It is a Tailslide with a Crail Grab, where the skater grabs the nose with their back hand, and is usually done frontside.
It is possible, but very difficult to do back Crails. The longer the slide the better it looks, so be sure to go fast and far.
Getting a full extension with the back leg is a pivotal part of executing a stylish slide.
