Are you considering this racquet ? I just bought mine y'day from mybadlookbad.com but I was rushing for time, didn't get it strung, will do it in Singapore instead. I was considering the new Millenium 8 X2 Blue, but that is more of an upgraded version of the X2 SP and it is flexy and 4U, hence I decided to get the AP instead. Anyway, Thailand don't have the new Millenium 8 series yet. Once I play with it, I will give you my feedback.
Well I read in this forum that M8 X2 blue has flexible shaft but I beg to differ, is fairly stiff on the one I possessed.I'm not particularly weak either but it does take quite a bit of effort to generate adequate club head speed or rather load the shaft. I prefer my matrix pro 168 seems to be more user friendly.
That's where the difference comes in, I saw reviews that the X2 Blue is flexy but the specs on RSL website states extra stiff. I guess only way to find out is buy one and test ! ha ha
