Well, shot my new 70# Onza this weekend. I gotta say, it was one of the easiest to tune bows I have ever had. Whisper quiet, very accurate, and a true pleasure to shoot. It's set at 73# from the factory, and is really zipping the arrows out there too. Now, I just have to figure out what's so different between this one, and my 60#er. There's a significant noise difference, and a bit of vibration difference. The 70# is the quietest bow I have ever shot, and the 60 is about average on noise. Gonna have to go over the 60 and my FC to see why they are not as quiet. Overall, a big thumbs up for the 70# Onza though. Might be taking it to Wyoming instead of my FC400.
