I have no proof to back this up....I am purely stating my experiences. I played with both the RDS 001 MP and Mid (Original Versions) - and thought they were decent sticks. Not great, but pretty good. In the past couple of weeks I have tried the Yonex 2008 updates to these rackets and I was completely blown away. They obviously have the same mold as the original versions. However first off they have a 'matte' finish as opposed to glossy which I MUCH prefer and looks much more stylish. More importantly they are probably the two most 'solid' yonex rackets I have ever hit with....and I have tried a lot of Yonex rackets. Obviously its subjective but I really do think that something in the lay-up of the frames have been tinkered with because to me these new ones feel absolutely great. Anyone else agree?? I am asking because so far most people seem to agree to that they are the same except for the newer PJ.
