A while back a friend came to our home to shoot with me on our rural back yard range. He commented on how quiet my 08 Firecat was during the shot. Later, he was visiting his brother in Florida who has a Mathews bow (not sure which one). While he was there he listened to his brother's bow and thought my bow was quieter than his brothers, at least from memory of what mine sounded like. I've also had a few others tell me they too think mine is remarkably quiet. About the only bow that I've shot that I thought might be quieter, or at least as quiet, was a $950 BowTech Invasion. It was nice to shoot but for the rather large amount of cash I'd have to shell out and for the very minimal, if any, improvement in shoot-ability and/or quietness I happily decided to stay with my Firecat. All in all I think it's a heck of a good bow that's especially hard to beat for the money.
A year ago I shot a Z7 while on a business trip to WA. It was a nice bow - no imperfections anywhere. It was also smooth and quiet. But, it was also nowhere near as fast as my Firecat and not that much quieter and way MORE costly.
So, based on what this 09 Firecat has I have little doubt you'd like it a lot.
