Yes its on one cable on that S-turn. The cables I made for my Revolt X with Angel Majesty don't have the slightest separation after thousands of shots. The Reckoning with some Powergrip has a little separation on that S-turn. Maybe next time I'll leave the string at 300 like you do. That is a rough area for sure and I'm surprised there aren't more issues with them.Is this on your Reckoning? That s-turn is brutal on serving.
I don't take tension off the string, but do back off tension on the serving jig.
