RE: G5 Peep sight???
1. If done correctly, yes....when you hook on to your D-loop, you will pull your peep square because you will have to twist the string to draw.
2. No. Simply doing the above will not train your string. You have to press the bow and put a 1/2 or full twist in the string. Because, every time you release, the string will return to it's original position.
Another thing you can try is this.....Take a strand at a time off of 1 side of the peep and move it to the other side. This will sometimes square them up.
