The Yonex Astrox 88D Game Badminton Racquet plays with better hold and power from the back court but also provides control and feel in the front court. Yonex has redesigned the ISOMETRIC™ head shape and added grommets with larger holes to promote greater string movement. This combination is very forgiving so you can play with maximum power. The classic Yonex T-Joint improves stability as you make contact with shuttles adding to the velocity on your shots. Overall the Yonex Astrox 88D Game Badminton Racquet is a powerful choice for back court players that want the racquet to give them a bit more power thanks to its medium flex shaft and head heavy balance.
