first of all- lose the brass nocks near the idler, weight there won't help with speed. your going to have to raise draw wt. or lower arrow wt. going to a new string like my razors edge strings that have no peep rotation will speed you up a feww fps. by getting rid of the tubing. they are $45.00 a set for single cam bows. third, make sure your bow is completely in factory specs.
