George, Dave is looking to draw the bow 28", Wile E is the one who made the comment about 32".
You have built a lot more white wood bows then me so I defer to you regarding the length this bow (61") will safely draw. With Osage, I routinely make stiff handled bows that push your 2 time the length rule, but not by much. My favorite length is 58-60" for my 29 1/2" draw. However, I have successfully built them as short a 56".
