To make a long story short, The Black Beauty Smoke has now was owned by a friend of mine that insisted he could cock it straight by hand. Caused me alot of head scratchin and sent what was probably a perfect V-zone back to D. Miller before I figured out what was up. At least mark the string at the rails, but I believe the rope cocker is the answer. You won't believe how much a teeny tiny bit off throws the arrow.
