Has any bodt shot Martin's new Viper yet?

I just read about these two guys who shoot a viper.

I shot one a month or so ago.It smoked an arrow but to me so far all the carbon limbed bows Ive shot make a"ping" type sound.Havent shot any with string silencers or limb savers though,Ill bet that would tone it down.I think theyre around 6 bills.
