The 100 Series of racquets offers the best possible combinations of durability and playability for a variety of budgets from that of a primary school to the equipment budget of a major university. Butt caps are double length, grips wraps are firmly glued to the solid wooden handles (two models even have a built in replacement grip) and all models have Longfibre badminton string and durable nylon grommets. It is important to remember that institutional models are designed for the rigors of institutional use and are usually not the best choice as personal racquets. Racquet covers are not included with 100 series models, whereas covers are included from the 200 series up.
