very nice blade. Easy to Handle. Pair it with T05 & T05-FX

Set up Fh: tenergy 64,
Bh: bryce speed
Good feel no vibrations. Tremendous control and was surprise for its blocking and pushing capabilities. Dwell time is excellent a little slow for flat drive.
But ovrall highly recommended.

Fatastic blade. I use it with two T05 2.1 and it's perfect, VERY good on blocks, very good control and also fast enough (faster than my TBS). Even if is not yet a best buy i reccomend to all offensive players,that wants a good control too.

i prefer this over the Viscaria, mainly because of the nicer handle. anyway the blade is 5.7mm and not 7.1mm....
Plays like the TB ALC IMHO. i cannot feel the difference between the two. i find that the TBS, TB ALC, Viscaria and ZJK to be very similar. excellent blade. currently using Nittaku Fastarc S-1 FH & BH.

I posted a review on this blade here:

A beautiful blade with great aspects.

The blade is light and well balanced. Costly but worth the investment. Give good dwell time due to its medium stiffness. I have Stiga Calibra LT FH and Tenergy 05 BH. Just love playing with this blade.

I played with the Primorac for a long time because it is a very good all-round blade. I didn't move up to a Primorac Carbon, some believe it is the follow up but it really is too big of a jump in speed, OFF- to OFF+. I decided to go with an OFF racket. I wanted significantly more speed though so I opted for an Arylate-Carbon racket. Between this and the Viscaria, I would say this is better due to the more comfortable handle. I use this racket with Sriver 2.1 on both sides.

I have played with my coach's Primorac Carbon before and it was very fast, due to the carbon fiber. You can see the thin black lines running along the edge. Here with the Zhang Jike, the lines are thin but alternate between blue and black. I guess the blue is the Arylate. Upon playing with it in a warmup I noticed no speed difference from my Primorac. This was disappointing. Then I started hitting harder, and suddenly the Carbon came into play. After that, even my soft shots had the power of Carbon.

The best comparison here is that the Arylate acts as a sleeping drug on the Carbon to give the blade more control. Hit softly in the warmup and you will have incredible control. Then you start hitting harder and you wake up the Carbon, suddenly all of your shots have amazing power behind them. Yet, the Arylate still stays in remnants, limiting the Carbon's power slightly but at a great benefit as it now still has a great amount of control.

Overall upgrading from an OFF- or just a wooden blade you will be very pleased with this blade. It took practically no effort to hit my normal flat forehands and spinny loops. This blade is absolutely amazing for loops. Once I started hitting with normal effort my loops were great, as fast as my previous loop kills. Of course when I hit a hard kill or a loop kill the ball was a bullet. And yet I could still place it where I wanted it. Great blade for loopers, you won't be disappointed. It had the power of Carbon but the Arylate makes it controllable. Buy this, you won't regret it.

UPDATE:
I have been playing with this blade for 6 months now... it definitely is very controllable and the speed is about as much as any intermediate player should need. The control is fantastic and so is the dwell time. If you want to counter left and right leaning over the table you can do that precisely. Standing well back from the table, you can execute spin-loaded loops right into the corners with more kick than cayenne pepper. Overall, if you want a looping blade, this is probably the best one you can get. It has a beautiful soft feel and enough dwell time to put tremendous amounts of spin and control on the ball, and the carbon layers give it enough speed to become atomic.

This blade is perfectly balanced, you can do everything with this blade, because of medium stifness and its superb control this blade is perfect with 2 T05 max! very good! This blade will become legend!
