All Howard Hill longbows are laminated, with fiberglass backing for a maximum of strength and durability. These straight-end longbows give you speed, stability and cast. They are feather light in the hand and have excellent maneuverability. Our bows will generally shoot a minimum speed of 115 feet per second plus the weight of the bow (i.e. a 65# bow should shoot at least 180 fps and may exceed that minimum considering variables in bow length, draw length, and arrow weight).
MAIL from :Easton Tech Support :I personally recommend going with something between 425-500 grains along with an 11-18% FOC. If you are between those ranges you will have a great arrow for big game. Just make sure that if you are using a lot of point weight on a 400 spine that you don’t make it too weak for your set up.
