The A7 is nice but needs to many after purchase mods for me. Cam work, new string and cables, and some times shooters ask for some type of grip tape on the risor. The c3 has been doing it all for so many years right out of the box you just can't doubt the living legacy of the top notch Mathews design.
The first time I shot a Conquest my good friend got one in at the proshop and set it up for hunting. I was shooting a Martin Cougar at the time and he was shooting faster and more acturatly than I was, and I was seriously impressed. I asked to shoot it and I had never shot a bow with so little vibration and great speed.
Great cam systems, very forgiving and parts are easy to get. The apex is touchy and the cam systems could use some work. That is not to say the A7 is not a great bow, it is. For the money though, I am going c3.
