Sounds not promising. Must be around 37g head weight. Luckily I didn't bought them. Is the JS10 stiffer than HX800? Some people rumoured crazy things, so I'm not sure, but actually I'm filling my piggy bank for a 4U JS10.
For me JS10 has more potential than the HX800 but its more demanding for the arm as it requiers a fast wirst acceleration to generate maximum power. Im not totally used to the HX800 timing so my opinion could still change.
Hi everybody. Last week I had a chance to test brand new 4U JS10 JP code and to be truth I'm disappointed. The stiff and the light weight make the racket swing fast so defend is very good, attacking on the net is ok but when using a lot of power from the wrist the racket shakes a lot, just like holding a hair clipper. I couldn't believe why such an expensive racket can be like that, my teammates at the court also tried and feel the same. The attacking I have to use quite more power then what I used to do when using the Bs12 3U. Overall I still recommend BS12 3U blue version and sticking with it. /IMO the JS10 4U is lighter and stiffer than my Bs12 3U.
That sounds very weird. I never experienced any shaking or excessive vibrations with the JS10. As it has been said several times in this thread, the JS10 likes a relaxed swing to achieve the best power with it. The more you try to force it, the less it delivers. At least that's what I have experienced.
Agreed. That's an extremely unusual observation that's far from the norm we've had reported so far...
