Would like to ask how is the weight different in these 2 models. Is it only the handle that is different (heavier)? Or the entire frame is heavier or denser. I'm asking cos I just bought an Asian spec one (they only have this over in asia) and like to custom it heavier to the US spec. On the grip size label, it's stated USL. Is there also a SL and L version (not sure which version is hte US spec one) of this and what's the weight like on them? So far, I've hit with the ncode and it isn't as solid feeling as my old PS 6.1 classic. My PSC 6.1 is the SL version - what's the weight on this? I presume the PSC 6.1 on TW now is the L version cos it's spec is heavier than the one I have now (coming in at about 340g strung and with overgrip). Can somebody enlighten me? Thanks! P.S. Does the US spec n-code 6.1-95 play as solid as the old PSC 6.1?
