dont tiller past the intended draw
dont hold it for 5 to 10 seconds,,
if you givinig it to someone,, shoot it more than 100 times,, and give them instuctions on how to shoot and care for the bow,,
if the bow is made well,,, and you had to hold it for a hunting shot, it will hold up, but no need to stress the bow out for no reason,,
if you are making the bow for someone that has a long hold,, then overbuild the design to accomodate that,,,,,
