Bob is right, a recurve is much more forgiving than a long bow. I shoot both but would recommend you start with a recurve. Also start out with carbon arrows with 4.5 to 5.5 inch feathers on your arrows.
Also check out the link to a thread I started on a backup bow I recently got. It is a great bow and it won't break the bank. In other words if it turns out you don't like shooting traditional, you aren't out a lot of money.
