[QUOTE="Steyr Luxus, post: 1282386, member: 29511"] Draw weight is not an indicator of bow efficiency. It is the force draw curve which indicates efficiency which is equal to the bows stored energy. If an 80 lb draw weight and a 60 draw wight bow have identical force draw curves (i.e. stored energy) and equal brace heights they have equal amount of potential energy. A balanced heavy for weight arrow has more potential energy than a light balanced for weight arrow driven at the same speed due to its heavier weight. The only advantage is that the lighter one will shoot flatter for longer distances. The potential energy advantage is still the heavier arrow. Additionally a heavy arrow will produce less noise upon release and buck wind better than a light arrow. The heavy for weight arrow will shed its speed faster. Therefore, the lighter arrow will retain a speed advantage but potential energy is still the the heavy arrow. To change the force draw curve most bow designers will use an eccentric cam type of wheel to get the max area under a force draw curve = more stored potential energy. To quote mtwarych "In todays age and technology, a big heavy draw weight bow is just not necessary." [/QUOTE]
