I recently switched back to hitting with this after a number of years. Compared to some of the other small headed rackets I used recently it feels a bit underpowered/dead, particularly compared back to back with the Dunlop Biomimetic 200 lite which has virtually identical specs. With both I have added 2-3g to the head, and have strung with signum pro plasma pure main, isospeed professional crosses at 52-54lbs. Any thoughts on how to liven up the response? Or is this just the way the PS 6.0 is?
