well ok,, I agree with pretty much all the advice,,,and only know what I know,,
but increasing weight on a bow is not that complicated,,
there are times when a bow is overbuilt,, that reducing the length ,,decreases the mass so that the bow actually shoots harder even if tillerd to the same weight,,,,not always ,, but sometimes,,,,, and as stated,, you can increase weight,, and the bow will take more set and off set the increase in weight,, but thats how we learn,,, if the bow is 72 inches long,,, and a low draw weight,,,there is some room to fine tune,, without having to build a new bow,,,, that being said,, ,, building new bow is good experience as well,,,
