This new development  is very effective at the table. Since it has a very control block for a powerful topspin. Allows even very fast attacks to be extinguished and returned to the table. At the same time, it gives a good rotation reverse and unpleasant creeping trajectories. In attack, he also shows himself well. And the undercutting protection in the far zone is comfortable, control and with a good reverse. The speed is about average, maybe a little above average. In general, the Doctor has developed another successful long spikes.
