The string on my tribute was making a slight 'twang' after the shot when i put on new cat whiskers. Instead of redoing the whiskers i added a STS. My bow went from shooting 298 fpsto 300 fps after i installed. Tested on the same chrono with the same arrow multiple times. Has anyone ever heard of this or could you explain why it happens?

The tech at the shop said that is common. I figured it would slow the string down a fps or 2.

PS. it definitely took care of the noise problem. I just ordered a MeanV CSS to replace the borrowed STS I used.
