Well I have always just used dowel rods for tracing,

It really has shown me that what I thought was correct wasn't, in the beginning my laser was pointing to far beyond the plane line, this was also happening during down stroke.

I was roundhousing into the ball and arching my left wrist, the wrist bar was really pushing up against my left forearm too hard.

For me personally I have been able to feel the correct left arm flying wedge and stop from arching my left wrist which is a big deal for me.
