Thanks for the reply. I have my own scales and have checked the weight and let off. The let off is showing 65% let off . It is supposed to be 80% but isn't . I know. I am going to take it back to them. I didn't get the bow from this bow shop though. They changed the Cam from a 29" to a 30" for me, but they told me it was a 80 % cam. I wrote the Mathews company, and they told me it was the right Cam. My Hoyt says 65% let off and it is when I check the weight and what I am holding. I need the letoff that is why I tried the Mathews. Have you ever tried your bow and see if the letoff is what the bow is supposed to be?
