My question is i am now seeing  new blades like the new Bridgestone Tour B X blades and the new Miura blade Mc-501 with a center mass behind the sweet spot and a shaved  down heel and toe to frame that center mass is this the new modern future blades and what are the benifits is it more forgiveness or better feel compared to more traditional blades with flat backs like a Tm p730 ,Mizuno mp 18 ,Cobra forged mb blades etc ?
