After re-reading my post, it looks like I came on a bit stronger than I meant to. Here's some more info and the reason I really would like for you to comment again if there are actual failures happening.

The people shooting thousands of shots I'm referring to are folks like a buddy Chad here, who originally got me interested in the Legacy/Icon design. He's a 3D shooter and shoots three or four nights a week, shooting about 200 arrows per night, about 80% of which are with his Icon that he has had since late January. That's a LOT of shots if you add it up. He's replaced the parts that you'd expect, but hasn't had any failures nor have any of his 3D buddies that he shoots with (3 others have Icon bows).

The reason I'm asking if you know of any specific failures is that my wife is buying me a Legacy for Christmas. She was going to surprise me, but finally broke down and told me she was buying me a bow because the sheer volume of info and the number of models out there was more than she could sort through. After a pretty long process of elimination, I decided on the Legacy. I'm planning on shooting it for a long time. If there are real examples of these problems in design causing actual failures, I sure would like to know about it before I spend that much money on one and am stuck with it for years to come.
