and WOW it is so fast and accurate.......put my scope on and tightened it down and went to sight it in and at 30 yds the it was dead on without any adjustment!.......i got one question though,i have the "fast string" on it and after about 15 shots i looked and the string had actually slid down about and inchtowards the limbs.....is this common and ifso do you just readjust the string once you see that or will it be ok>?
