LCW is using VT ZF for few months already! To me, SW35 is a very stiff racket and very demanding as compared to VT ZF which I can feel the flex when swinging. VT ZF is more friendy than SW35. I think they are the same in term of power. My 2 cents
ZF is a very stiff and head heavy racquet, more stiff and headheavy than Voltric 80. Yeah it has awesome power but IMO it is not a racquet for everyone. Have not tried SW35 but I doubt it will be more demanding than VTZF. My 2 cents
I've tried the SW35 and briefly tried the VT ZF! The ZF feels way more head heavy! I found the SW35 more user friendly in regards to being a better all rounder. The VT ZF will be better suited for more a singles attacking racket. Didn't test any longer as it wasn't 'my cup of tea'!
