I'm not sure about the CX's but an experience I had yesterday has proven the Maxima's. My son was shooting my bow, 64# 28" with a 350 Maxima. He was shooting at 50 yards. He missed the target high bounced off the ground and went through BOTH sides of my neighbors metal building.[
] Of course it was thin metal, but I'm still shooting the arrow. No cracks, period.
