Bona, I can only pull to 26" and the bow I made is for 28". I tillered it out to 29" and shot it at my 26". That's all we can do. Osagetree(Joe Weed) is left handed but I can't shoot that way so I shot it right handed.
I usually leave a newly completed bow strung for 2 to 6 hours to "sweat" it, basically controlled stressing.
