Yes, at your draw length, you would want a bow marked about 43#@28 inches,if you're buying an already made/used bow. Since you draw to 29 inches, it will pull about 45# plus at 29 inches.
Most production bows are marked in 5# increments, but you can specify the draw weight at a given draw length if you have a bow custom-made. Some bowyers might change the limb stack (i.e., thickness and taper of the laminations, maybe the thickness of the glass,etc.) when making bows for specific draw lengths, but most don't. They just mark the bow weight at the draw length ordered.So, if you order a new bow made to draw 45#@29 inches, that's what it will be.
