I have both NEXY EKITA PRO 51 & NEXY EKITA PRO 47.
There is only a slight difference between them IMHO.
Both to me play very close to Tenergy 05 with the 47 being slightly softer and a little bit bouncier
As ever its all subjective.
However i can currently get Nexy rubbers cheaper than...
T64 backhand and Z2 forehand was my set up until very recently. T64 is softer and faster. Z2 to me plays almost exactly the same as T05. It is of course all subjective however. Have never used MXP as I prefer Japanese rubbers.
As ever its entirely subjective. Blade used, playing style, technique etc, all of these will make it unique to the user. I don't feel its stiff or has a low throw angle
