Hi NL,
I have played with both of these rubbers, GT a while ago now, it was the 1st 'hybrid' that I used.
SPIN - all have high spin potential.
TACKINESS, when new RZ / RZ EH are similar to GT, but I think GT retains its tackiness levels better than RZ / RZ EH
THROW ANGLE - RZ highest, then RZ EH then GT.
SHORT GAME, all are easily controllable, but the throw angle is reversed somewhat, with RZ you may find that you'll have to open face more when pushing v backspin.
SERVING- well, maybe slightly easier for short serves with GT. that little extra 'catapult' of the Rakza's may need MINOR adjustments for 1/2 long serves. great spin for all 3.
SPEED - difficult to compare - indirectly, maybe R Z is faster than R Z EH which is faster than GT, of course this depends on what you put in, but there's not much in it really!!! Lets say they are all fast enough to hit past opponent!!!
LOOPING!!, BH and FH, safest with R Z , then R Z EH then GT - throw angle again!!!! all dip down rapidly, none have that H3 'low kick' but all have excellent spin production capability, so no issues there!! you may find that RZ's sponge kicks in more with harder shots.
AWAY from the table - R Z ie easiest to play with, the sponge kicks in easier, it's definitely not as 'dead' as either R Z EH or GT.
WEIGHT - they are all heavy!!!!!!
To sum up, RZ EH will be closer to GT in my opinion. this is probably the one out of the 2 Rakza Z versions you'll prefer. (now I've said that, what's the betting you'll prove me wrong!!)
I really like RZ and RZ EH used them on and off for 3 years or so, last season I used the Rakza's for 90% of matches.
now using H8-80 on BH and Jekyll & Hyde H on FH (52.5 sponge), playing better with the H8-80 on BH.
As always, take above with a pinch of salt, YOU only know when YOU try it out!!!
Enjoy testing them, and get H8-80 37 and 38 degree versions, oh and Tau 2 and .........
😂
but seriously try the H8-80 if you can.
