I played with this rubber(39° FH[50gr], 37 BH[50gr]) yesterday without any booster on HL5(90gr blade, total 190gr). It was decent rubber. The catapult felt like Battle 2 prov. blue sponge.
I couldn't generate powerful backspin on serves, but side, side backspin was effective. Easy to do short no spin serves to backhand (very effective against those who flip every ball)
Pushing short/long/varying was pretty easy after T19.
Strong open ups was easy to do without worrying my technique/bat angle etc. Slow ones weren't dangerous as fast ones.
2-3 step behind the table was also not an issue to play topspin. But I struggled to play counter topspin because of catapult. Whenever the topspin from opponent comes little short and/or little more spin, rubber effected by topspin alot and catapulted too much. Maybe less springy and a stiff blade would be better for this purpose, like TBALC.
I reckoned a problem with catapult. It is like there is a pretty inconsistent range in terms of power and spin. I know it is not a linear rubber but to explain it super scientifically:

It felt useless to play %60-%80 power. It is like ball is already gone without spinning enough. Maybe I get used to its characteristics, but playing at medium power should be done wisely, else it is pretty disadvantageous.
On the backhand I need more time to get use to play at medium pace after playing with ESN rubbers. The topspins were powerful, but trajectory was too long for good enough spinned shots. It shoots pretty fast and sharp. Maybe equal to full power BH shot with TBALC and T05. Again mid speeds was only good for keeping the ball on the table, if you ignore opponent smashing that returns
I lost to a guy who playes basic drive with long serve and keeps the ball on the table. It was really hard to play backhand consistently. That was mostly my problem, but rubbers play also role at various balls.
Against long pimple defensive player(close to table) was too easy after T19. I spinned almost every ball without problem.
I guess, BH is not the right rubber for me. I have to be able to play at mid speeds. It is necessary at my level. Therefore today I am going to play with Hybrid MK(45gr) on BH to eliminate my inconsistancy.
