I have a Mathews Switchback xt..29.5 draw..68 lbs..I shoot carbon express blue streaks 350.. 4 inch feathers...Ripcord arrow rest..string loop..scott release..100 grain tips.. I can not get a tear left out of my bow.. It doesn't matter what I do to try to achieve this, same result...tear left..I moved my rest out from straight to about 1 inch out of line same result..tear left..I also moved rest way in to try to get a tear right,same result ..tear left.. Up and down with the rest/nock point is perfect. I put lipstick on fletchings to see if they were hitting but they were clearing everything.. I paper tuned with bare shaft,fletched arrows and still same results..I have been really watching grip pressure,but no matter how i hold its still the same about 1 inch tear left.. Checked cam lean with arrow, perfect with string. When shooting targets,any length,arrows show nock left.Some cam lean at full draw but nothing out of ordinary..NEVER had this before this year..Checked limbs, no cracks..Would twisting cables/string help?? Went to a couple of bow shops and couldn't figure it out. Just looking for any advice..Thanks for any and all advice..
