Well said. Yeah this trick is all about whether or not you are a mack at back 3's. You have to be able to do them perfectly in order to land on the rail and stay on the rail. Explaining all of the mechanics to a back three on would take forever so I'll try to simplify it. You have to throw it with as little of edge dig as possible, as straight as possible, be early enough with your spotting that you can set it in, and again, don't huck it and cut into it.
