Absolutely worth every penny you spend on a good quality jig and fletches. Somebody has probably figured it out but even if it costs more it is still worth buying raw shafts and building your own you won' t believe the difference in your arrow flight especially if you have trouble with your broadheads. you will still get slight difference' s in the raw shafts but put them aside and use for target only. If you don' t get into it too much it is still worth buying a GOOD QUALITY jig jo jan bitzenburger and there are some others, it will pay for itself just by fixing your knock around arrows.
