I am shooting the '09 X-force Super Short (26" ata). The bow is a tack driver! I had nock pinch at first (29" draw combined with a short ata places the string on a very acute angle when fully drawn). I resolved the problem by serving both my top and lower d-loop knots in place-providing adequate room for my arrow nock. Now, the bow shoots like a dream. I look forward to taking her to Prince of Wales Island in ten days. More results pending...
