I have a 07 Diamond Triumph which I am now selling because of this, or should I? Long story short I shot my buddies 07 Commander, and I could not miss, however I had just gotten back from deployment and have just picked up my bow after Cabela's had it, (which i now regret) I have tried everything I just can not get it sighted in. The string looks like it may need to be replaced and I have shot it a total of 8 times after today, so I am going to order those get it setup again, sell it and just pick up a new bow, or maybe I will like it after the fact, anyone have opinions on a new bow, or anything that would lessen my frustrations with this bow?
