RE: Longbow draw weight
As suggested,you can get by with a stiffer spine for center cut bows andwill need alighter spine for knuckle shooting, or bows that are not shot through the riser. Its hard to say a perfect weight. Id suggest you get some close as you can, B.C. has made some good suggestions, then tune the arrow to the bow. Get them rather long, since you have a gorrilla draw (lol. So do I, im 6'4" with just over a 30" draw myslef) and change up the head weight or cut the shafts to tune them. All in respect to bare shaft readings. Good luck.
