RE: String ?
If the limbs aren't twisted,you're probably torqueing the bow when drawing.You should be drawing straight back from the centerline of the riser to your anchor.If you're drawing a little off to one side or the other,or not drawing back in a straight line with the riser--the limb is gonna torque off to that side.If you grab the limb-especially when strung,you can twist it from side to side very easlily--a longbow won't torque like that.That's one of the reasons I think a longbow is a more forgiving bow to shoot.
