Greg,

Great post. I do not know how I missed this back in September. I have been using a similar setup for about two years now. I have found it to be very effective with a variety of the bows I have used it on.

However, like several of the others have mentioned both the laser and the levels have their faults. This particular laser's faults have been fairly well described. However, the riser's flatness in relation to the bow's string travel isn't the only issue. The laser does a good job of aligning the bow in its static state...at rest. Dynamically, the shot process involves many variables, not the least of which being shooter induced, that directly affect the various tuning "settings".

The levels' biggest fault typically shows itself when part of the level sits on the bare string and part sits on the center serving. It can throw the desired setting off if you do not compensate for it.

Don't get me wrong on these products. I do not like or utilize papertuning much either. I think the products you mentioned can be an excellent starting point for most shooters (and can get you very, very close for some bows) but many times a little additional tweeking is also required...something you made mention to earlier in the thread.
