: I only use the laser pointer because I happen to have it. It is the size
: of a fat ball-point pen. I just shine through the same holes that I had
: the strings through. If it still comes out the other end, I know things
: haven't shifted too much

Thats the same thing I was wanting to do but couldn't find the laser pointer when I was aligning. My son bought it from another kid at school. We did find a great alternate use for it later on, the cat loves to chase the light around the room. My son calls it the remote control for the cat.
