I Thought Once My String Was Broken In, I Could Reset My Peep And Proper Alignment Would No Longer Be A Concern. I Do Have What They Call A " Pro Release System" Which Is Consists Of An Aluminum Nock Device And String Loop Combination. However, I Have Never Used It Because It Weights 45 Grains And I Thought It Would Have A Significant Effect On Arrow Speed. Has Anyone Used or Heard Anything About Them? Any Thoughts Or Comments Would Be Appreciated.
