@JanMove and Outside2:
I really have played with Nittaku and don't find them top, as they do not grip as good as Donic and Andro in my opinion.
TSP I played yesterday and (although I lost

I find them as good as Andro, but not as good as Donic.
@Roland (from England) and Sascha Eichmann:
The DHS I have never seen and tested .....
(You see, I am not a profi

)
Have you tested all the four balls and can give a statement on the "grip" of these balls ?
Remark:
(Nittaku I
have played and I personally think tehy are not as good as TSP, Andro and especially Donic).
