I have shot longbows for many years and just about every brand. You will find out that a longbow that is 66 to 70 inch long will pull easier than a 58 to 64 inch longbow but they are slower in cast. I use to shoot a 90 pound Howard Hill 70 inches long and it's arrow speed was 170 feet per second with a 650 grain arrow. Because of old age and neck and back trouble I had to go down to a lighter poundage. I now have a Longbowbow from Wildfork Archery that is 64 inches long and 62@26 and a Morrison takedown 64 inches long and 70@26. I got 175 feet per second with the Wildfork longbow and 172 feet persond with the Morrison. Much easier to pull and faster. If your draw is over 27 inches look for a 66 inch bow this will handle nice for you. You can shoot a shorter bow but to get the most out of the bow the tables would reccomend a 66 inch if over 27 inch. Poundage is another question only shoot what you feel comfortable with. Remember Longbows do not have the cast that most recurves do and they are longer so shooting position is more important. Canting the bow will allow you to shoot from about any position with practice. Check out Wildfork Archery Van makes a Longbow that is very fast and gracefully crafted.
