This rubber was amazingly precise on my bh when used with the stiga emerald vps penhold blade (as i am a penholder). But some problems when i flip my racket and use it on forehand. When start playing on mid to far distance it always direct the ball to the net. For me its good on flicking, agressive counter attack and bh drive. My opinion this rubber suits more for bh than fh. Spin is ok. Weight is far lighter that the non-FX version and its also controllable.
