I currently own a voltric 7 and previously owned an arcsaber 5.
With my voltric 7 I feel more in control and have more power and accuracy.
For me my arcsaber didn't really help or hinder me, but my voltric helped me a lot.
Also for the price of the voltric 7 it really is amazing.
see if you can find both from someone and borrow them and hit with them and see which one feels better. i enjoy playing with arc7 because the weight and balance fits my preference, but that's just me, might not be the same for you.
it would be easier if we know what you're using right now and why you want a new racket and the things you don't like about your current racket and things you want in your new racket.
See earlier i had carbonex 7000df which is a light head racket recently my friend bought voltric 5 and i played with it and i was amazed by its sheer power maybe i loved it bcz i play a bit offensive thats why somewhere in my mind i feel head heavy rackets are my cup of tea but at the same time ive heard great reviews for arc7 from my friends and on the net so im in a state of dilemma
They are not the same level so nobody should compare. Should one compare a BMW 1-series to a Suzuki Swift?
Arc 7 is high-end and Voltric 7 is mid-end, yr carbonex 7000df seems to be low-end (i'm not too sure, just guessing). If it is made in china, then those are the low-end of Yonexes. Any of the above racket should be better than your current racket.
