Laymen's terms;

A laser is only going to be as straight as the machining on the side of the riser. If the path of the string/arrow and the levelness (pardon the ghetto word) of the riser are not dead nuts with each other... you'll have crooked results.

Moreover, no matter if your form is perfect or flawed... its still your form.. and still your grip on the bow. You need to tweak it to YOU!!!! The YOU aspect is something that no bow tech can really tune for.. unless of course you are shooting with them standing behind you.. which you will pay for of course.
