The Ektelon EXO3 Ignite is offered with "Original Inserts" located at 12, 3 & 9 o'clock on the frame. These inserts all weigh less than the extra Grey "Custom Inserts" included with the racquet. Therefore, adding Grey inserts to the frame will increase weight in the specific location where the insert is installed on the frame. This allows the weight of the racquet to vary from 170 grams to 180 grams and the balance point to range from 2 pt. head heavy, even balance or 1 pt. head light. The Ektelon power level for this racquet ranges from 3900-4000.
