So many great long bows available today. My personal favorites are Pronghorn bows out of WY & Horne's Archery out of TX, but there are a lot of other great ones. Personal preference is huge when choosing any trad bow so getting to shoot as many different ones as possible before deciding is a big help. Some bows just "feel" right for an individual and the next guy likes something totally different.
If you draw 27" with a compound you will probably be about 26"-26.5" with a trad bow. They are often rated at 28" so if you are looking at a used bow figure about 3# per inch to get close to what it would be at your draw. A 55# @ 28" bow would be around 49# - 51# at your draw. Although you shoot a 70# compound, going too heavy with the first trad bow is maybe the most common mistake guys make. 50#-55# is plenty for hunting and you will have more fun.
With a 26"-27" draw I would go no shorter than 60" in a longbow. Some folks like shorter bows, but the string angle at full draw can get severe and that can make for a poor release. Longer bows can feel smoother but now a days there are some very smooth short bows as well. If you go over 64" they can be hard to maneuver in a treestand or other tight quarters, but more traditional longbow styles are often, well...long. If you are getting one built, the bowyer will guide you on what length fits your draw length, desired weight, and his design.
All that said, you might pick up a bow that fits none of the criteria I just gave and it will "feel" great. That trumps everything.
Have fun!
! But if you Must spend the money and don't mind the time to get one ,look at Ron La Clair's Shrew longbows.Dick Robertson out of Mt. makes quality bows. Check out 3 rivers archery supply, they have bows ,books and dvd's.
