Ok, I found a post where you were selling your Xforce, this is what I'm basing things on.

07 xforce
33" ata
6" brace
26 inch draw length
73 lbs draw weight
kisser button
peep sight

And I'm going to assume you are using 4 inch vanes on your arrows.

I will get back with you in a while with what I come up with.
