I had two fingers rolled back inside my palm and two fingers gripping the bow, I moved one more finger inside my palm and tightened my sling.
And then I read something about creating torque by holding the string or the arrow to close to your face, so I put my peep higher and let only the tip of my nose touch the string and voila my st axis arrows fly straight and I can begin adjusting my sight.....

thx once again everyone who listened and helped me out, I'm one more step closer........
