I have an 08 Cheetah 70# 27" draw, this bow was so loud abd vibrating so hard when I first got it and shooting inconsistant. After checking, and re-checking and checking again and launching one of my factory installed string leeches out of my string, I had the string leeches served in. I also noticed that my arrow vanes were hitting my cable where the cable guide is. Called Martin and they sent me a different cable guide and it moved my cable at least 1/8 in. over and out of the way. This bow shoots so smooth with little or no vibration or noise and deadly accurate, like totally different bow !!
