The trade-off when using a group of pulleys is primarily between mechanical advantage and increased complexity. While a system of pulleys can significantly reduce the amount of force needed to lift a load, it may also require more rope and increase the overall size and weight of the setup. Additionally, the added friction and potential for energy loss in the system can reduce overall efficiency. Thus, while pulleys can make lifting easier, they also introduce challenges in terms of design and practicality.
