I am shooting a 2009 bowtech captain 29'' draw at 70 lbs. with a qad drop away rest and my arrows are cx maxima hunters 350 spine and are 29'' with 125 gr tip. My problem is when I shoot a bare shaft from about 15 ft. it always hits the target at an angle with the nock end going to the left. I moved the rest all the way in both directions shooting at intervals and it only changed point of impact, the arrow was still hitting with the nock to the left. I could get the angle alittle smaller but could not get it to go away. I think the spine is wrong but not sure if to weak or to stiff. Any info is appreciated.
