I think they slap too, but we are certainly in the minority. Over on Archerytalk, there are some guys who would just as soon neuter you for saying anything that's not totally positive about the STS. For the record, I had mine as much as 1/2" away from the string, and could never find the "sweet spot." The bow I used it on was a Darton, which are known for vibration and noise. Go figure.
