A friend of mine just bought an Alien X. I'm trying to help him get it to specs and set-up. Any idea how many twists it'll take to get 1/2 inch out of the ATA? Also, should I add a couple twists to the string when taking up that much cable length? It's currently setting at 32 inch ATA and 7 1/8th BH. Draw weight is 69# Thanks guys!
