You can shoot that Montana with the Schulz methods, the shape of the Montana grip may add a half inch or so to your draw length, compared to the saddle or straight gripped Hill style bows. Your draw length is what it is, some folks get themselves in a tizzy targeting draw lengths. While out pheasant hunting this year with shoot away but sharp broad heads in my quiver, i proved to myself once again that a 42 @ 26 ASL will shoot a 27" bop wood arrow straight through an Iowa whitetail. My go to deer hunting bows are a duo shelf 50@26 JD Berry and a 55@26 duo shelf Sunset Hill. The 42 pound bow was a 51 pound Hill Big Five before I attacked it with a rasp, files and sandpaper, in an attempt to get the draw low enough for my wife. remember to add 5pounds to the arrow spine minimum for a modern string. I personally shoot quite a bit above the dynamic charts with my duo shooters, that spine reduction do to being outside of center does not seem to apply with my cedar and Surewood arrows, they fly online and fly straight and steady. If you prefer to shoot with straight armed recurve form, you may like a new recurve better.
