After some careful modelling, I selected ACEs, size 670, as I was confident that I would be able to use them with the same draw force, changing just the pressure button at most.

    In Bow 157, I provided an overview of how I model arrows. I consider them as inextensible, flexible beams consisting of many short sections joined together. Each of those sections has its diameter, mass and stiffness. I showed how I determine those parameters for each arrow type and size.

    In this article I will provide an overview of how that modelling can be used to study the arrow’s dynamic behaviour during the bow’s power stroke
