Thicker rubbers are not as energy efficient as thinner rubbers but they do store more energy so one can return a faster or spinnier ball. I would recommend that the thickness of the rubber should be proportional to how far back from the table one plays most of the time.
That's a point you have there, Peter.
Last week I just had an interesting read on another forum, saying that certain blades just don't give you a nice feeling and feedback and start feeling numb if you put on too thick rubbers, but also vice versa other blades don't feel nice with too thin rubbers as well.
I didn't know what to think of this. It was the first time i've heard that.
Would be interesting to know, what you guys think of that.
Well anyway, after having thought and re-thought about this from my very own experience i think i agree with Vossi on the rubber thickness point.
Here's why:
*story-mode-on*
I've learned playing in 38mm era where 2.5mm speedglue-play was normal. (with all that glue on it, it probably was 2.8mm)
but nowadays 2.1mm is totally fine for me.
When i started i had a friend who was really good, and was sponsored by a japanese brand. He didn't use rubbers longer than a week and many times gave me his "old" 2.0 and 2.5 rubbers. So i adapted to it and my friend coached me and taught me a few things.
Meanwhile the coach at our club to that time was his older brother, who actually wasn't very pleased with my rubber selection, since i've just started playing a couple of months ago, but as he saw how quick i adapted he was okay with it, knowing i didn't have a lot of money and used to play with chinese rubbers before that.
But then after about 2 years the coach had to quit due to his studying at a different university.
So then this old coach came up who was between 55 and 60 y.o. and playing a chopper's game with 1.0mm bty tackiness and an anti on bh.
And he asked if i was crazy using these thick rubbers and made me change to 1.5 FH and 1.3 BH.
He was mostly teaching us pushing, blocking and not a lot topspin, which got totally boring after a while. But my teammates and me did have a lot of control while pushing.
But one of my close friends was playing for a club at the neighbours town which was a Bundesliga Club where even Guys like Georg Böhm played for a short time.
And they had a more modern vision of teaching tabletennis. Most of their youth players were playing how i had before with 2.0 BH and 2.0 sometimes 2.5mm FH.
Well i got good at pushing and blocking and straight balls but not so much in spinning, whereas my friends from the neighbour town were spinning balls with rocket speed and massive rotation that found their way on the table with the precision of heat-seeking-missiles.
In the longer spin to spin rallies i just couldn't compete with a "quick-bottoming-out" 1.5mm rubber.
After a couple of years when i started finding this out, i went back to thicker rubbers and told the coach to let me play with what i wanted to play with.
He probably only accepted, 'cause he anyway was about to retire after that season and our club hired a new coach teaching us a more modern game and he was totally fine with thicker rubbers being used by us.
*story-mode-off*
So from my own experience thick rubbers suit an offensive game way better. It might be different if you want to become a chopper, but not very many seem to become one and that's never been an option for me too.
'Cause just like NextLevel and Upsidedowncarl: i like putting 'heavy' spin rotation on the ball...
