I'd like to respond to pdq5oh and say..."ya, it's the grip, shoulder, or whatever else." And I've beat myself up over this thinking I was the problem. Unfortunately...I've shot a few other short draw bows, short axle bows, as well as a lot of longer, more traditional bows...and whatever issues I've had, they'be barely affected my arrow flight and poa.

With the dually.... when it was on...it was on... I couldn't make it screw up via grip, shoulder, etc.

I'm thinking I've got the stuff handy...I'll probably video tape myself shooting and call out where the hits are. Possibly then I can spot shooter problems. If they aren't apparent, I'll look at the bow some more

I'll ask about a new string as I know the dealer makes them... I'm not ready to pull the plug on this shop just yet (but may shortly).
