It is not apt to untwist if you leave it on the bow. Let it slide down the top limb rather than take it off. String keepers work good too. Once you get it set where it is the quietest and shooting the best, measure it and write it down. It is good practice to mark an arrow with a painted ring so you can tell at a glance every time you nock it, if anything has changed. If you had to twist it enough to raise it 1 and 1/2" You still could have used a little shorter string. It wouldn't hurt to run that by them also. Don't know why they missed it so bad to start with and still didn't come any closer. Measure the string length when it is twisted to the right brace height. That is the length you need. >>>----> Ken
