The Radical MP feels lighter than the specs reflect. Its lighter head-weight allows one to swing faster--if you have a fast swing and desire some additional control without going to a lighter, ultra-stiff frame, this frame would be great. If you are currently using a frame that is heavier, there will be an adjustment to one's serve & base-line shots. An NTRP of 3.5-4.5 would benefit from the additional quickness this frame would grant at the net in doubles. While somewhat lighter than my preferences, if I weren't getting older & crankier, this could easily become my next racquet of choice!
