sorry for no info. mathews MQ32 29in. draw should be 70lb pull but can only get it to 64lb it' s A single cam. I know the string was streached out I shoot alot every day so I twisted the string & the cable It feels good but I noticed it' s little louder then before witch should be expected right ? like going from heavy arrows to light? even after doing string & cable still 64Lb ? is this all I can get. I' m afraid to make it shorter might put stress on lims.
