Ive got unbacked osage and elm bows 50" long with ridged handles that I regularly draw to 26.5" with absouloutley no problem. In fact they both still hold unstrung reflex. If you put sinew on that little sucker I wouldnt be scared to take her back to around 26" You just need to see how your string angle is going to be, you dont want to pull it past 90 degrees at full draw. In another words the bow should tell you how far its willing to go.
