Thank you @victormanriquey for a very nice and thoughtful collection of blog posts — I have now indulged in all of them.
Glad you enjoyed them and thanks, if this helps people that's all that matters
It seems that you recommend around 52–54° hardness on the forehand, even for beginners. I find this both interesting and intriguing.
As someone with many, many hours of table tennis in my body from childhood, now returning to the game at 40+ (much like the ball), I recognise very well the tendency to overthink equipment.
Yes I'm a bit old-school 'chinese philosophy' in a way, I enjoy hard tacky rubbers and have seen the positive effect they have on beginners many times. I have also have seen how very soft rubbers have the opposite effect. However, this is a very personal matter, and many people disagree with me here, that's fine
One thing that cannot be disputed though, because is science, is that with the forehand you can use your body much more than the backhand where the body is in the way and because of the ball's speed. In tennis is easier to use more body on backhand, but in TT it is not easy when close to the table. This is why I believe that for the forehand you dont need the rubber to help you as much and you can go for a harder/tackier sponge. If engaged correctly, a harder sponge (due to the composition of pores, walls, pips) will always give more spin than a soft one that bottoms out. This is the principle, but of course, plenty of nuance in the middle. Anyways, that's why hard tacky FH, and medium/softer on BH (so tensor helps you out with spin/speed when body cannot). Also, most chinese players do this too and they are the best in the world. Don't think it's random
And yeah, overthinking equipment is a thing, specially for people who like me, have a natural tendency to overthink. There seems to be plenty of us in TT, god knows why, maybe the sport attracts our kind, that's a different topic for another day, probably requires its own thread haha
One rubber that is mentioned frequently — and very positively — is Xiom Vega China. Since you invited comparisons, especially to Hurricane 3, I would like to point to @doppelmoral ’s very thorough
blog review with detailed comparisons to several rubbers, including H3.
Yes I am going to add that to the blogpost, I think it's a good addition and a very good review. I have only tested it once and a long time ago, I cannot really remember the feeling I had fully or the blade it was on, pity, so for this I will trust the blogpost
I think it can work for BH, just like 09c fits for BH well too, but not for a beginner or intermediate, you need to have a notion of hitting through in backhand before you can use this effectively in my opinion. Effectively is the key word here, a rubber can always be used
Do you think forehand rubbers can or should “trickle down” to the backhand as players improve?
I have observed this happening with Dignics 09C and Glayzer 09C quite often. Conceptually, this could be a way to only “half change” parameters when upgrading equipment. Or do you think this is a flawed principle altogether?
No i think there is truth in this, specially if you have used those on FH before and are upgrading the forehand to something harder tackier, no problem at all. If you like the hard tacky/semi-tacky feeling of 09c but wanna swap it to BH and get a H3n on FH or so, I think that's perfectly fine. Many people use 09c on forehand and think it's plenty hard, so I think again a matter of philosophy and personal preference, but I see no issues in principle with that.
You mention Glayzer 09C as a hybrid forehand option, but referring to the reasoning above, this (and Dignics 09C) is something we quite often see on the backhand of experienced players. So why not include a hybrid category for BH as well? Which leads me to:
Regarding the backhand specifically:
I am a bit surprised that you do not list hybrid rubbers as a separate BH category. Personally, I am currently playing MK-FX and Nuzn 45, which feel surprisingly similar on the backhand. Both give me exactly that combination of tacky control with a mild tensor effect that, in my experience, the backhand often benefits from.
I do have the BH section on hybrid, it says Hybrid/Chinese haha but I have not added Nuzn 45 because I have not tried it before (I have tried a couple rasanters though) and was under the impression that for a beginner moving to intermediate it may be too fast? If you can ellaborate on that, I'm happy to add that into the mix, and MK is already in there, but with a word of caution to beginners

And I agree, i like hybrids on BH, I follow that line of thinking too.
In another thread about Hurricane 3, it was described as “a young man’s rubber”, referring to the amount of physical effort required to fully unlock its potential. Thinking about myself, I realistically have another 10–15 years to continue developing technique and the _right_ kind of physicality — but always in a battle with time. Improvement at this stage is less about acceleration and more about continuity.
H3 (or similar hard/tacky rubbers) is for sure more demanding than many other rubbers, even if boosted, but with the correct technique you will feel it in the legs, core and condition, not so much on arm or wrist

So if you play relaxed and only explode on right moments, it's a bit more doable. I still sweat like a beast every training session though (I play non-stop 3h or so xD)
