just go for it! lol. id shoot for a lower draw length. youd be surprised what a piece of wood can do, if its a good piece and you work it right. i took a piece of red oak, 48 inches to about 25 inches before it blew up. that was with a non bending handle. ive currently got another piece of red oak board 55 inches, pulling to about 27.5, non bending handle. just go slow. like they say, practice makes perfect, if you aint breaking, you aint making, and so on and so forth! lol
