RE: string loop
benhunting
If you tie on the " D-loop" using the correct procedure, the loop material (stretch factor) dictates the size of loop (distance from string). You get what you get.
A. Using a " loop" will ALWAYS change your draw-length to a degree; and can change your anchor, draw length, and draw-weight. Easily adaptable vs. extreme is the gauge.
B. If the loop is too long but you maintain your normal anchor, your bowstring draw-length will now be less and that could affect the draw-weight of your bow and the " spine to draw-weight" of your arrows.
C.. On the other hand, if the loop is too long and you pull off your normal anchor to put your bowstring in a position you normally did -or need to e.g. string-peep, kisser button, etc, your draw-length will most likely be too long and several other problems are going to occur. Your grouping and accuracy that you may have had is going to go to Hell in a hand-basket, instantly.
1. Use a loop brand/material/type that has a reputation of limited stretch. I like the BCY and Brownell rope material available through TRU BALL with the " SPEED LOOP" nock aligner.
2.Tie your " loop" onto your bowstring so that the loop is flat against your bowstring.
3. Once tied, feed a long piece of high-strength cord through the loop.
4. Grasping the cord in a manner that will allow you to pull the loop without losing grip of the cord, pull until loop stretches enough to allow your release to connect to the loop.
5. Shoot several rounds until your loop appears to have reached maximum stretch.
6. When you believe the loop has maxed out on stretch, check to determine if loop size is not going to radically change your form and your bow' s performance. If the loop is too long, try a different loop brand/material.
7. If loop does not stretch enough to allow release to connect, or to connect without butting against the arrow nock, tie in a new loop using the additional length required.
After I determined that I was getting a consistent and acceptable stretch out of a particular material, I shortened the barrel on my mechanical release so that my anchor remains the same and my draw-length change is negligible.
