Looking at the pictures, the frame oval looks more like the Z-Speed. As earlier comparisation, the head oval from the Z-Speed was different compared to the Z-Slash and Z-Speed. Maybe they integrated some Z-Speed technology in the ZF2.
Did the ZF already had the thinnest shaft? If so, there is nothing new about this fact.
I seen this racket today, as our yonex rep had it, sadly I never got to try it but did compare it with my ZF
The shaft is quite a bit thinner than my Z Force
The Head shape seems very small, however may be due to it being very oval shaped
Bill (Yonex Rep) said the racket feels a bit more head light compared to the ZF and a little better on the shoulder compared to the 3U ZF
He said the racket feels a bit similar to the 4U ZF
The one he was using was UK coded 3UG4
I use a 4U VTZF
Before I was buying them I tried the one that he had which was 3U and it was majorly hurting my wrist when I was trying to do defensive shots, maybe because it was factory strung but it felt a bit too weighted so I opted for buying the 4U
4U at the start hurt my arm a little getting used to the stiffness and the racket, however after playing with it now for a month and a bit the pain I was getting at the start has completely gone and feels natural, feels like i'm getting more power compared to when I was using the VT70
i always have this mentality...i always go for a heavy headed racquect and do my best to master it and play it like a light headed racquect....having a heavy headed racquect is always an advantage...and is how you improve yourself phisically and technically to adapt and use a heavy racquect efficiently...
i have been using ZF since Febuary 2012...1st impression was very very good...control and power...after 2 hours of playing you start to mishit and have bad control as you get tired physically and you are not able to keep up with the heavy head racquect...and i do get some sore shoulders and arms...then i try to improve my technical skills and i no longer have aching issues...and i am used to the weight now and could control the racquect for longer period...but there are few times when the racquect nearly slipped of my hand due to the head heaviness and wet grip...another thing is...i found that my ZF stiffness is not as stiff as it was 1st when i got it..either i physically adapted to it and i also believe that the stiffness will reduce as the more you use it the stiffness will reduce more n more due to wear and tear like a rubberband...yeah a good equipment/racquect will prolly affects maximum 15% of your gameplay...but its fun to master a good racquect that is not easy to play with...its a challenge...but its a bit sad that the stiffness reduces...meaning after wear and tear i dont get the actual stiffness it was meant to be
Yeah man ! I used to like head heavy and stiff racquet with high tension but with age, I find it tiring and tough to handle those racquets. My preference now is mid stiff and fast racquet. A fast racquet is really a god send especially when your speed and reaction is on the down turn.
Singles definitely go for heavy racquect...cos u have all the time in the world to swing it...for doubles especially if you play in front too much...try to play with a light racquect...dont stay too close to the net...once u r comfortable move a bit infront...always keep the racquect up...once u have your reaction confidence back...then u can try using a heavy head...
Actually racquect is a very light tool...even a piece of paper will start to fell heavy if u hold it ling enuff...regarding the pain...i believe its mostly due to the technique...from what i learnt...nv force returning hard a shuttle above or over you...if u use a hammer properly...u wont feel its hard...but when u swing it the wrong way it hurts u....as long as u move and anticipate faster than the shuttle and always be infront of the shuttle...you should be ok...and wheb u hit a shuttle it suppose to be parallel to you...its all about positioning yourself fast enuff to be able to hot the shuttle efficiently...
