That's what we call the long string, one that fits loosely. Most guy's will go to a short string after the limbs bend evenly to about 8-10" draw. The short string could be used as the permanent string, you just want to make sure you don't brace the bow too high at first stinging, 3" brace height is good, Just enough to check string alignment. One of the easiest ways to miss your desired weight is to spend too much time on the long string, the weight isn't the same as short string. I don't mind helping, that's how I learned.
