Draw weight is the amount of force required to pull the string back and is determined by the construction of the arms. Adding fins would do nothing to increase the draw weight.

High draw weight is achieved using the right materials; for example composite bows are constructed from layers of flexible wood, rigid horn, and elastic sinew. The combination of rigid horn wih elastic sinew stores greater energy than wood alone. The horn compresses, the sinew stretches, and when released it springs back with greater force.
