Dunlop have aimed the FX range as the great all round racquets , plenty of power but now with a spin enhanced string pattern and plenty of forgiveness built in to the frame via some very good engineering. We have great feedback on our demo's they are rating as high for 6/10 for our customes who have tried this frame. This frame compares quite favorably to racquets like the Pure Drive and Speed models. Well worth a demo if your are looking for that 300G type frame
