Like someone else said, the best way to to twist/untwist the string a twist or 2, maybe just half, and get it lined up. It's easy to do if you have access to a press. When you mess with it, you'll see what it takes to get it perfect when you start twisting the string. Then once you get it lined up, set your d-loop so it's lined up with it, then take some d-loop pliers and cinch that sucker down good and tight and your set.

And if your d-loop is made of the camo material, you'll never get it as tight as you could with the solid color BCY stuff. I've hunted and shot target with bcy loop material and tubeless peeps for years with good strings. Not one issue after thousands of shots. I'll never go back to the tubing peep again.
