Hmmmmmmm, I got myself a Moon 12 Blue in M- hardness for BH since why not.
I didn't particularly like the H-, especially not on BH side. It's also a bit heavy for BH, and since the sponge was hard it was hard to use it. What I liked in it was the insensitiveness to incoming spin, which is not a bad thing for a lefty on BH side especially on higher levels.
So I got the M- which by feeling is I guess 47-48deg ESN? It doesn't feel softer than G1, but it feels bouncier than G1. To me the H- on BH just didn't wanna bounce or go but the M- is easy to use.
I've been using Mantra Pro M on BH which is about 47 degree hard, so the M- in hardness felt comparable; tho the Mantra Pro feels more airy and the Moon Blue M- feels more rubbery.
I guess I have been complaining about the H- grip before, and on BH I'm pretty sure I was not wrong since it's difficult to sink the ball into the H- sponge. I did not have this issue with M-, I can sink the ball and it has more than enough grip, I never felt any lack of grip with M-.
What I liked about the M- on BH is the ease of use, the really good bounce, like I say I think it's more than G1, but less than Mantra Pro M , it has very good grip, hell I think the sheet is very slightly tacky. I would say it's like a "shadow of a fart" tacky. Very good for blocking since insensitive, great for serve receive.
But to my surprise, it's not bad for making open-ups and banana flicks. Flicks are easy since the rubber eats the ball and doesn't drop it like some rubbers. Even if I do a weak or slow flick it doesn't drop the ball.
With ESN or Japanese rubbers the harder you flick the better your result, but if you don't do the flick hard enough the ball will fall out from the rubber and into the bottom of the net.
Open-ups are interesting since even weak open-ups are possible and while some would say those are not dangerous well I don't think so, mixing very spinny open-ups and open-ups with barely any spin is not that easy to deal with. Against high spin you need to force the ball down our you hit it long against low spin ones if you do the same you will hit the ball in the net. It's actually good deception. I also had pretty great success with varying sides or down the middle open-ups with different spins and speeds.
I think the M- is a pretty good replacement for your typical 47deg ESN rubber or Japanese rubber. My backhand is pretty good but still Moon M- makes me feel comfy.
