Viper is dead in the hand,very little if any shock/vibration,very quiet,solid wall,smooth draw,very accurate and fast short ata single cam bow.
Most comfortable bow I ever shot,to each their own on feel though.
I could'nt be any more pleased with it.I sure wish I could afford another APA. Black mamba 7.5 would be a nice addition to my gear.
I jumped ship from PSE,so thats gotta say something,PSE make great bows too.
