I believe my Martin Mambas are a good bit shorter than that. The extra lenght in a recurve or long bow makes for a smoother shooting bow.
Kathy, can I assume you won't be hunting with it? If you will be, some states have a minimum draw weight allowed to hunt, usually around 45lbs for deer.
Kathy, if I were you, I would go to an archery range and ask them to shoot 40-50 lb bows. You will need to do this over a two week period if possible in order to get an accurate indication as to what you can handle.
Shooting traditional bows you will use muscles you never knew you had and your body will be sore the first few days or so. Its like lifting weights, you will have to go through an adjustment period, so if you can, get to the range before you purchase a bow that will be uncomfortable or underweight to shoot.
If I had to pick a draw weight for you it would be 45lbs, but you may be able to handle 50.
Have fun and best of luck!
