better late then never just to give my (modest) opinion. I used all sorts of dampeners, I tried the head smartsorbs, the head logo, the techfiber clips, the rubberband (the staples ones) the etc... and then i got back to not using any...and...the vibration, or "ping noise" (no doubt in my mind) or whatever caused me to be wearing a elbow stress relieve elastic band (that´s a fact)...yup...dont know if your all right or wrong..but for me is back to dampeners just in case (the facts dont lie dont care what anybody says) and a "decathlon" (dont know if you have it in the states but is a big franchise in EU) smile dampener is in my strings (2.95 Euros for 2)! Use it or not (for cosmetic reasons)..that´s not the question! PS: i use a head flx radical mp. Ps2: I´v been playing from 22 years .. only 6 moths ago I stopped using dampeners (20 y ago we used pieces of rubber that we used to cut our selfs). Just another fact!
