RE: String turning ?
All good advice. I have personally never seen a Bowtech string not settle down after 50-100 shots, but it is possible.
Regardless of the string, I always shoot mine 50-100 shots without a peep to settle them in. Then stick the peep in and see what adjustment needs to be made. As Greg mentioned, you'll probably find that you need to add a twist or two to the string to get it just right. Shoot it a bit and see what happens. It will usually only move a little after this and you can usually compensate for it with your D loop.
