I shot a Berry String for the last 5000 shots on my bow. The peep never moved and the quality was excellent. If it wasn't for a slip with a razor blade trying to move my peep up I'd still be shooting it. The Ultra cam was really stable and didn't fuz up at all.

For my new string I went with a Wolfden String in TS1 since Wolfden is now the stock string maker for my Newberry bow. I'm very happy with this string also.
