Well, I am thinking there is no need to make such a complicated stuffs.. since i am developing a 2 shift . Maybe a good idea to use a bench type of straight bar instead? could they be the same?

IMO there is a lot of danger in using a bench type of straight bar.

1. The club is contact at only one point, allowing for tilting, head down, hands down, etc....
2. Without a plane surface it is difficult to monitor the alignment of the hands (which IMO is the Biggie after the straight plane line)

A Solid surface can open a whole new perspective on your golf stroke.

Note, I am not a proponent of monitoring the clubhead, I think if 3-F-5 alignments are set,then it should just be the hands to plane that should be used as check points, not the clubface, but that is just me...
