Well my bottom cam and string are toast on my Z7. I will also tell you carbon fiber splinters hurt and sting real bad when you pull them out. Heres the story. I was sitting in my TreeWalker stand and a large doe and three small ones come buy just as the sun is starting to set. Lead doe keeps looking up at me so I dont stand just wait for her to pass to get a quartering away shot. I draw get her in the sight and pull the release trigger. I here this awful noise and my bow about jumps out of my hand. I see the nock and flecting end of my arrow fly off to my left. Look at the bow and string was off the cam. The cam was rotated and a big chunk was out of it. When I shot the cam hit the shooting rail of the stand. I climb down find my arrow shaft and the other part with the fletching. There was about 2" missing in between the two parts. I had some of that in my left hand when I removed my glove. Luckily didn't go in to deep and pulled right out. I called my dealer on the way home from the woods and he is gone on a hunting trip. I have to call back tommorrow as he has a guy coming in to work at the shop for him while he is gone. Hopefully they have and extra cam and string so I can get it put back together. I took vacation next week to hunt and this could really put a hurt on that. Just had to vent a little still kinda steaming as to how I could have done that.
