I like my Pro Tools 105, but I have a problem keeping multiple bends that are "on the same plane", on the same plane. My bender is level according to my level but try as I may I usually have to "cut and turn" to get things where they're supposed to be. What is the secret? I've tried to find a digital level to use on the bent end of the tubing when making a second or third bend, but no can find.
