Let me clarify the factory specs on the 2007 were 32" ATA and the 2010 was 32-1/4. When I received the 2010 the specs were wrong. They twisted my string too much and it was under 32"(specs 32-1/4). That is too much pre-load. My bow is not the only one that was like that in that year there were many. The strings were terrible and they twisted some too much and others too little. Just look at the cam timing on martinhunter's. This was typical to see in pulling them out of the box. It is simple just untwist the string to its specified length and the same with the cable. Then adjust accordingly. That is what I did with mine. And now the specs are all the same as factory. The bow preforms quiet, fast, and properly.
