Ya should always take them and shoot them to be sure. Privuded the bow is is tune, the cams are timed and centershot is on point they should be [beeep] close.
The most important factor provided that someone knowledgeable sets the bow up is that the arrow spine is spot on. To weak/stiff and youll never get them to both impact the same.
I'm a string builder and Ive tuned more then my share of bows. Good luck!
