LM Radical Tour provides more Power, more stability, and is more forgiving (a really bigger sweetspot clearly better when you hit off center), the feel is a matter of personnal taste but I for myself would say both racquets provides good feel when you hit the sweetspot but the Lm Radical MP Tour still provides a better feel on off center shots. The LM Radical Tour feels slightly less flexible (but I repeat : only slightly), but is more comfortable due to the bigger sweetspot and extra stability. The LM Prestige MP provides slightly more maneuverabilty but the 2 racquets are very close in that sector.
Even if the first week I played "dreaming tennis" with the LM Prestige MP, I finally realised that the LM Radical was a better racquet, less demanding without any sacrifice about the control, allowing me to play excellent tennis on a more constant basis.
