OK guys here is the rest of the story........

I found my arrow and it was downrange and intact. I found a Hoyt dealer that actually had a clue and he measured my harness and string and inspected the wheel, cam and limbs and everything seems OK. I shot about a 100 arrows last night with no problems, so I am going to assume it was a fluke and not worry about it to much. There is not a whole lot I can do at this point as the bow shops in my area don't have any 31" bows in stock anyways and season is only a few days off. Just in case I am sighting in my old PSE and taking some time to shoot it a litlle bit .... just in case of emergency.

Thanks for all the input......
