In this week i tested Rakza 7 on TB ALC and T05 on Primorac.
Point 1: Tenergy kind of expels the ball faster than Rakza, I didn't feel that it engages the sponge very much, Rakza "holds" a little more I believe this must be due to the fact of hardness too, T05 is slighty harder and more dense. When i do force with my body it is clear the speed difference and this effect of "kicking the ball out", Rakza give me a lot more control because it holds the ball more on contact, i was not able to have a "deeper" contact on the sponge while using Tenergy.
Point 2: I felt that it is necessary to use less force with the tenergy, but FOR ME, and for MY PLAYING STYLE this is bad. When i moved about 3m away from the table to test the fh topspin with more loop, it was clear how much the tenergy does the work (speed) on its own, i had to control how much force my body did. When I tested the Rakza from the same distance it was clear the greater amount of control, Rakza is slower and I also feel the ball stay more in the racket, I could do much more force and have an even more satisfactory result.
In general on FH i prefered Rakza 7 for my playstyle, much more control and the capacity of have this deep contact when i perform the stroke is better for me, T05 FOR ME is too fast and does too much the job. On BH, T05 is better for me, Rakza becomes more slow.
