Well, I tried to shorten my string and got my brace to 6 1/2 " but went from 61 lbs. with the limbs bottomed out to 57 lbs. I tried to lengthen the buss cable and take the twist back out of the string and the brace went to 6 1/4" but I still only have 57 lbs. I' m starting to get a little angry. I tried to call Mathews but they were to busy to talk to me so I left a voice mail and they haven' t called yet. My bow press will not allow me to take the string and cable off to measure. Anybody got a guess[:' (]. Don
