Will a G2 get out of time as the string streches? My opinion is that the factory string is junk.

Absolutely. As with any traditonal single cam bow the timing of the single cam will definitely change as the string stretches. The quality of the factory installed strings on the NAAG bows in general seems to be mixed. I am wondering if they have changed string manufacturers recently.

How do you check the timing on a g2 or single cam bow?
